--redirect-url=https://oauth2-proxy.example.com/oauth2/callback
--oidc-issuer-url=https://<keycloak-host>/realms/<realm>
--email-domain=example.com
--code-challenge-method=S256
```
:::note
Keycloak has updated its admin console and as of version 19.0.0, the new admin console is enabled by default. The
legacy admin console has been announced for removal with the release of version 21.0.0.
For Keycloak versions earlier than 17, include the legacy `/auth` path in the issuer URL:
```shell
--oidc-issuer-url=https://<keycloak-host>/auth/realms/<realm>
```
Optional authorization examples:
```shell
--allowed-role=<realm-role-name>
--allowed-role=<client-id>:<client-role-name>
--allowed-group=/engineering/platform
```
:::tip
If Keycloak is behind a reverse proxy, make sure Keycloak's configured hostname and proxy headers produce the same issuer URL that OAuth2 Proxy uses in `--oidc-issuer-url`. Issuer mismatches commonly happen when Keycloak advertises an internal host, the wrong scheme, or the wrong context path in its OIDC discovery document.

**Keycloak legacy admin console**
## Keycloak client setup
1. Create new client in your Keycloak realm with **Access Type** 'confidential', **Client protocol** 'openid-connect'
and **Valid Redirect URIs** 'https://internal.yourcompany.com/oauth2/callback'
2. Take note of the Secret in the credential tab of the client
3. Create a mapper with **Mapper Type** 'Group Membership' and **Token Claim Name** 'groups'.
4. Create a mapper with **Mapper Type** 'Audience' and **Included Client Audience** and **Included Custom Audience** set
to your client name.
In the Keycloak admin console:
**Keycloak new admin console (default as of v19.0.0)**
1. Go to **Clients** -> **Create client**.
2. Set **Client type** to **OpenID Connect**.
3. Set **Client ID** to the value you will use as `--client-id`.
4. Enable **Client authentication**.
5. Enable **Standard flow**.
6. Disable **Direct access grants** unless another integration requires them.
7. Add the OAuth2 Proxy callback as a valid redirect URI, for example `https://oauth2-proxy.example.com/oauth2/callback`.
8. Save the client and copy the client secret from the **Credentials** tab.
The following example shows how to create a simple OIDC client using the new Keycloak admin2 console. However, for best
practices, it is recommended to consult the Keycloak documentation.
### Audience mapper
The OIDC client must be configured with an _audience mapper_ to include the client's name in the `aud` claim of the JWT token.
The `aud` claim specifies the intended recipient of the token, and OAuth2 Proxy expects a match against the values of
either `--client-id` or `--oidc-extra-audience`.
OAuth2 Proxy validates the token audience. Configure Keycloak to include the OAuth2 Proxy client ID in the token audience:
_In Keycloak, claims are added to JWT tokens through the use of mappers at either the realm level using "client scopes" or
through "dedicated" client mappers._
1. Go to **Clients** -> `<client-id>` -> **Client scopes**.
2. Open `<client-id>-dedicated`.
3. Click **Configure a new mapper** and choose **Audience**.
4. Set **Name** to `aud-mapper-<client-id>`.
5. Set **Included Client Audience** to `<client-id>`.
6. Enable **Add to ID token**.
7. Enable **Add to access token**.
8. Save the mapper.
**Creating the client**
If your upstream services require additional audiences, add them deliberately. Keep the `aud` claim limited to intended token recipients.
1. Create a new OIDC client in your Keycloak realm by navigating to:
**Clients** -> **Create client**
* **Client Type** 'OpenID Connect'
* **Client ID** `<your client's id>`, please complete the remaining fields as appropriate and click **Next**.
* **Client authentication** 'On'
* **Authentication flow**
* **Standard flow** 'selected'
* **Direct access grants** 'deselect'
* _Save the configuration._
* **Settings / Access settings**:
* **Valid redirect URIs** `https://internal.yourcompany.com/oauth2/callback`
* _Save the configuration._
* Under the **Credentials** tab you will now be able to locate `<your client's secret>`.
2. Configure a dedicated *audience mapper* for your client by navigating to **Clients** -> **\<your client's id\>** -> **Client scopes**.
* Access the dedicated mappers pane by clicking **\<your client's id\>-dedicated**, located under *Assigned client scope*.
_(It should have a description of "Dedicated scope and mappers for this client")_
* Click **Configure a new mapper** and select **Audience**
* **Name** 'aud-mapper-\<your client's id\>'
* **Included Client Audience** select `<your client's id>` from the dropdown.
* _OAuth2 proxy can be set up to pass both the access and ID JWT tokens to your upstream services.
If you require additional audience entries, you can use the **Included Custom Audience** field in addition
to the "Included Client Audience" dropdown. Note that the "aud" claim of a JWT token should be limited and
only specify its intended recipients._
* **Add to ID token** 'On'
* **Add to access token** 'On' - [#1916](https://github.com/oauth2-proxy/oauth2-proxy/pull/1916)
* _Save the configuration._
* Any subsequent dedicated client mappers can be defined by clicking **Dedicated scopes** -> **Add mapper** ->
**By configuration** -> *Select mapper*
### Test user
You should now be able to create a test user in Keycloak and get access to the OAuth2 Proxy instance, make sure to set
an email address matching `<yourcompany.com>` and select _Email verified_.
Create or update a test user and ensure:
**Authorization**
- the user has an email address matching your `--email-domain` setting,
- the email is marked as verified, unless you intentionally configure OAuth2 Proxy to allow unverified email addresses,
- any required roles or groups are assigned to the user.
_OAuth2 Proxy will perform authorization by requiring a valid user, this authorization can be extended to take into
account a user's membership in Keycloak `groups`, `realm roles`, and `client roles` using the keycloak-oidc provider options
`--allowed-role` or `--allowed-group`_
## Authorization
**Roles**
OAuth2 Proxy always requires a valid Keycloak login. You can further restrict access with Keycloak groups, realm roles, or client roles.
_A standard Keycloak installation comes with the required mappers for **realm roles** and **client roles** through the
pre-defined client scope "roles". This ensures that any roles assigned to a user are included in the `JWT` tokens when
using an OIDC client that has the "Full scope allowed" feature activated, the feature is enabled by default._
### Roles
_Creating a realm role_
* Navigate to **Realm roles** -> **Create role**
* **Role name**, *`<realm role name>`* -> **save**
A standard Keycloak installation includes mappers for realm roles and client roles through the predefined `roles` client scope. These roles are included when the client has **Full scope allowed** enabled, which is the Keycloak default.
_Creating a client role_
* Navigate to **Clients** -> `<your client's id>` -> **Roles** -> **Create role**
* **Role name**, *`<client role name>`* -> **save**
Create roles as needed:
- Realm role: **Realm roles** -> **Create role**.
- Client role: **Clients** -> `<client-id>` -> **Roles** -> **Create role**.
_Assign a role to a user_
Assign roles to a user from **Users** -> `<username>` -> **Role mapping** -> **Assign role**.
**Users** -> _Username_ -> **Role mapping** -> **Assign role** -> _filter by roles or clients and select_ -> **Assign**.
Authorize realm roles with:
Keycloak "realm roles" can be authorized using the `--allowed-role=<realm role name>` option, while "client roles" can be
evaluated using `--allowed-role=<your client's id>:<client role name>`.
```shell
--allowed-role=<realm-role-name>
```
You may limit the _realm roles_ included in the JWT tokens for any given client by navigating to:
**Clients** -> `<your client's id>` -> **Client scopes** -> _\<your client's id\>-dedicated_ -> **Scope**
Disabling **Full scope allowed** activates the **Assign role** option, allowing you to select which roles, if assigned
to a user, will be included in the user's JWT tokens. This can be useful when a user has many associated roles, and you
want to reduce the size and impact of the JWT token.
Authorize client roles with:
```shell
--allowed-role=<client-id>:<client-role-name>
```
**Groups**
To reduce token size, you can limit which realm roles are included for a client: **Clients** -> `<client-id>` -> **Client scopes** -> `<client-id>-dedicated` -> **Scope**. Disable **Full scope allowed**, then assign only the roles that should be emitted in tokens for this client.
You may also do authorization on group memberships by using the OAuth2 Proxy option `--allowed-group`.
We will only do a brief description of creating the required _client scope_ **groups** and refer you to read the Keycloak
documentation.
### Groups
To summarize, the steps required to authorize Keycloak group membership with OAuth2 Proxy are as follows:
Authorize group membership with OAuth2 Proxy's standard `--allowed-group` option.
* Create a new Client Scope with the name **groups** in Keycloak.
* Include a mapper of type **Group Membership**.
* Set the "Token Claim Name" to **groups** or customize by matching it to the `--oidc-groups-claim` option of OAuth2 Proxy.
* If the "Full group path" option is selected, you need to include a "/" separator in the group names defined in the
`--allowed-group` option of OAuth2 Proxy. Example: "/groupname" or "/groupname/child_group".
To emit Keycloak groups in tokens:
After creating the _Client Scope_ named _groups_ you will need to attach it to your client.
**Clients** -> `<your client's id>` -> **Client scopes** -> **Add client scope** -> Select **groups** and choose Optional
and you should now have a client that maps group memberships into the JWT tokens so that Oauth2 Proxy may evaluate them.
1. Create a client scope named `groups`.
2. Add a mapper of type **Group Membership**.
3. Set **Token Claim Name** to `groups`, or set it to another claim name and configure OAuth2 Proxy with `--oidc-groups-claim=<claim-name>`.
4. Decide whether to enable **Full group path**.
5. Attach the `groups` client scope to your OAuth2 Proxy client.
Create a group by navigating to **Groups** -> **Create group** and _add_ your test user as a member.
If **Full group path** is enabled, include the leading `/` and full path in OAuth2 Proxy:
The OAuth2 Proxy option `--allowed-group=/groupname` will now allow you to filter on group membership
```shell
--allowed-group=/groupname
--allowed-group=/groupname/child-group
```
Keycloak also has the option of attaching roles to groups, please refer to the Keycloak documentation for more information.
If **Full group path** is disabled, use the group name as it appears in the token.
**Tip**
## Verifying token contents
To check if roles or groups are added to JWT tokens, you can preview a users token in the Keycloak console by following
these steps: **Clients** -> `<your client's id>` -> **Client scopes** -> **Evaluate**.
Select a _realm user_ and optional _scope parameters_ such as groups, and generate the JSON representation of an access
or id token to examine its contents.
Use the Keycloak console to preview tokens before debugging OAuth2 Proxy:
1. Go to **Clients** -> `<client-id>` -> **Client scopes** -> **Evaluate**.
2. Select a realm user.
3. Generate an ID token or access token.
4. Confirm the token contains the expected `aud`, `groups`, `realm_access`, and `resource_access` claims.

| `invalid audience` or failed audience validation | The OAuth2 Proxy client ID is not in the token `aud` claim | Add an audience mapper for the OAuth2 Proxy client and include it in the ID token. Also include it in the access token if upstreams use that token. |
| `issuer did not match` | `--oidc-issuer-url` does not match Keycloak discovery or token issuer | Use `/realms/<realm>` for Keycloak 17+ and `/auth/realms/<realm>` only for older Keycloak. Fix Keycloak hostname/proxy settings so discovery advertises the public URL. |
| `--allowed-role` does not allow the user | The role is missing from the access token | Ensure the `roles` client scope or equivalent mappers are assigned and the user actually has the realm/client role. |
| `--allowed-group` does not allow the user | Groups claim is missing, uses another claim name, or group path does not match | Add the groups client scope, configure `--oidc-groups-claim` if needed, and match the full path format used in the token. |
| Browser receives very large cookies or NGINX returns header/buffer errors | Tokens contain many groups or roles | Reduce mapped claims or use Redis session storage instead of cookie-only sessions. |
## Legacy admin console notes
Older Keycloak versions used the legacy admin console and the pre-17 `/auth` context path. If you still operate those versions:
1. Create a client with **Access Type** `confidential`, **Client protocol** `openid-connect`, and **Valid Redirect URIs** set to the OAuth2 Proxy callback URL.
2. Copy the secret from the client credentials tab.
3. Create a **Group Membership** mapper with **Token Claim Name** `groups` if you use group authorization.
4. Create an **Audience** mapper with **Included Client Audience** set to your OAuth2 Proxy client ID.

Provider for Microsoft Entra ID. Fully compliant with OIDC, with support for group overage and multi-tenant apps.
Provider for Microsoft Entra ID. It uses the Microsoft identity platform OIDC endpoints and adds OAuth2 Proxy support for Entra-specific features such as group overage, multi-tenant allow-listing, and Workload Identity client authentication.
Use this provider for new Microsoft Entra ID deployments. The legacy [`azure`](ms_azure_ad.md) provider is deprecated and should only be used for existing installations that cannot migrate yet.
## Choosing the right configuration
| Scenario | Recommended configuration |
| -------- | ------------------------- |
| Single tenant, no group authorization | `provider="entra-id"` or the generic [`oidc`](openid_connect.md) provider with tenant-specific issuer |
| Single tenant, group authorization with up to 200 groups in the token | `provider="entra-id"`, enable groups claim in the app registration, use `allowed_groups` with Entra group object IDs |
| Users may have more than 200 groups | `provider="entra-id"`, enable groups claim, request Microsoft Graph delegated `User.Read`, and grant consent so OAuth2 Proxy can resolve group overage through Microsoft Graph |
| Multi-tenant application | `provider="entra-id"`, use the `common` issuer, set `insecure_oidc_skip_issuer_verification=true`, and restrict tenants with `entra_id_allowed_tenants` |
| AKS or Kubernetes without client secrets | `provider="entra-id"` with `entra_id_federated_token_auth=true` and Azure Workload Identity |
## Config Options
The provider is OIDC-compliant, so all the OIDC parameters are honored. Additional provider-specific configuration parameters are:
| Flag | Toml Field | Type | Description | Default |
| --------------------------- | -------------------------- | -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| `--entra-id-allowed-tenant` | `entra_id_allowed_tenants` | string \| list | List of allowed tenants. In case of multi-tenant apps, incoming tokens are issued by different issuers and OIDC issuer verification needs to be disabled. When not specified, all tenants are allowed. Redundant for single-tenant apps (regular ID token validation matches the issuer). | |
| `--entra-id-federated-token-auth` | `entra_id_federated_token_auth` | boolean | Enable oAuth2 client authentication with federated token projected by Entra Workload Identity plugin, instead of client secret. | false |
| Flag | Toml Field | Type | Description | Default |
| ---- | ---------- | ---- | ----------- | ------- |
| `--entra-id-allowed-tenant` | `entra_id_allowed_tenants` | string \| list | List of allowed tenant IDs for multi-tenant applications. When not specified, all tenants that pass token validation are allowed. Redundant for single-tenant apps because regular ID token validation already matches the tenant-specific issuer. | |
| `--entra-id-federated-token-auth` | `entra_id_federated_token_auth` | boolean | Enable OAuth2 client authentication with a federated token projected by Azure Workload Identity instead of a client secret. | false |
## Configure App registration
To begin, create an App registration, set a redirect URI, and generate a secret. All account types are supported, including single-tenant, multi-tenant, multi-tenant with Microsoft accounts, and Microsoft accounts only.
## Configure an app registration
Create an app registration in Microsoft Entra ID, set an OAuth2 Proxy callback URL, and choose either a client secret or federated credential for client authentication.
### Microsoft Entra admin center
1. Open the [Microsoft Entra admin center](https://entra.microsoft.com).
2. Go to **Identity** -> **Applications** -> **app registrations** -> **New registration**.
3. Choose the supported account type for your deployment:
- single tenant for one organization,
- multi-tenant for multiple organizations,
- multi-tenant plus personal Microsoft accounts if you need both Entra tenants and personal accounts.
4. Add a **Web** redirect URI for OAuth2 Proxy, for example `https://oauth2-proxy.example.com/oauth2/callback`.
5. After registration, copy the **Application (client) ID** and **Directory (tenant) ID**.
6. For secret-based auth, go to **Certificates & secrets** -> **Client secrets** and create a secret. Copy the secret value immediately.
7. For group authorization, go to **Token configuration** -> **Add groups claim** and include the group types you want in ID tokens.
8. For group overage handling, add Microsoft Graph delegated `User.Read` to the app registration and grant consent according to your tenant policy.
9. For Workload Identity, configure a federated identity credential instead of creating a client secret. See [Workload Identity](#workload-identity).
OIDC scopes such as `openid`, `profile`, and `email` are requested by OAuth2 Proxy in the `scope` setting. Microsoft Graph permissions are API permissions on the app registration and may require user or admin consent.

### Configure groups
If you want to make use of groups, you can configure *groups claim* to be present in ID Tokens issued by the App registration.

## Groups and authorization
To authorize with `allowed_groups` or pass groups to an upstream application, enable the groups claim in the app registration. Use Entra group **object IDs** in `allowed_groups`; display names are not stable identifiers and are not what Entra emits in the `groups` claim.
```toml
allowed_groups = ["ac51800c-2679-4ecb-8130-636380a3b491"]

### Scopes and claims
For single-tenant and multi-tenant apps without groups, the only required scope is `openid` (See: [Scopes and permissions](https://learn.microsoft.com/en-us/entra/identity-platform/scopes-oidc#the-openid-scope)).
### Group overage
To make use of groups - for example use `allowed_groups` setting or authorize based on groups inside your service - you need to enable *groups claims* in the App Registration. When enabled, list of groups is present in the issued ID token. No additional scopes are required besides `openid`. This works up to 200 groups.
Microsoft Entra ID includes up to 200 groups in a JWT. If the user is a member of more groups, Entra emits an overage indicator instead of the full group list. OAuth2 Proxy detects that indicator and calls Microsoft Graph `/me/transitiveMemberOf` to add the user's groups to the session.
When user has more than 200 group memberships, OAuth2-Proxy attempts to retrieve the complete list from Microsoft Graph API's [`transitiveMemberOf`](https://learn.microsoft.com/en-us/graph/api/user-list-transitivememberof). Endpoint requires `User.Read` scope (delegated permission). This permission can be by default consented by user during first login. Set scope to `openid User.Read` to request user consent. Without proper scope, user with 200+ groups will authenticate with 0 groups. See: [group overages](https://learn.microsoft.com/en-us/security/zero-trust/develop/configure-tokens-group-claims-app-roles#group-overages).
For group overage to work:
Alternatively to user consent, both `openid` and `User.Read` permissions can be consented by admistrator. Then, user is not asked for consent on the first login, and group overage works with `openid` scope only. Admin consent can also be required for some tenants. It can be granted with [azuread_service_principal_delegated_permission_grant](https://registry.terraform.io/providers/hashicorp/azuread/latest/docs/resources/service_principal_delegated_permission_grant) terraform resource.
- add Microsoft Graph delegated `User.Read` to the app registration,
- include `User.Read` in OAuth2 Proxy's `scope` when it needs to be requested during sign-in,
- ensure the user or an administrator can consent to that permission.
For personal microsoft accounts, required scope is `openid profile email`.
Without the required permission and consent, users with group overage may authenticate successfully but have no groups in the OAuth2 Proxy session, causing `allowed_groups` checks to fail.
See: [Overview of permissions and consent in the Microsoft identity platform](https://learn.microsoft.com/en-us/entra/identity-platform/permissions-consent-overview).
Personal Microsoft accounts do not support the same Entra group model. Use group authorization and group overage handling for work or school accounts in Entra tenants.
See:
- [Microsoft identity platform group overage claims](https://learn.microsoft.com/en-us/security/zero-trust/develop/configure-tokens-group-claims-app-roles#group-overages)
- [Microsoft Graph transitiveMemberOf](https://learn.microsoft.com/en-us/graph/api/user-list-transitivememberof)
- [Overview of permissions and consent](https://learn.microsoft.com/en-us/entra/identity-platform/permissions-consent-overview)
## Scopes and claims
For single-tenant and multi-tenant apps without groups, the only required OIDC scope is `openid` (see [Scopes and permissions](https://learn.microsoft.com/en-us/entra/identity-platform/scopes-oidc#the-openid-scope)).
Common scope choices:
| Scenario | Scope |
| -------- | ----- |
| Work or school account, no groups | `openid` |
| Work or school account with group overage support | `openid User.Read` |
| Personal Microsoft accounts | `openid profile email` |
| Multi-tenant including personal accounts and group overage for Entra tenants | `openid profile email User.Read` |
Use `oidc_email_claim`, `oidc_groups_claim`, and `oidc_audience_claims` only when you need to override OAuth2 Proxy defaults. For Kubernetes RBAC and other systems that need stable user identifiers, consider using the Entra `oid` claim via `userIDClaim` in AlphaConfig.
## Multi-tenant apps
To authenticate users from multiple tenants, including personal Microsoft accounts, use the common issuer and disable strict issuer verification:
### Multi-tenant apps
To authenticate apps from multiple tenants (including personal Microsoft accounts), set the common OIDC issuer url and disable verification:
```toml
oidc_issuer_url=https://login.microsoftonline.com/common/v2.0
insecure_oidc_skip_issuer_verification=true
provider = "entra-id"
oidc_issuer_url = "https://login.microsoftonline.com/common/v2.0"
insecure_oidc_skip_issuer_verification = true
```
`insecure_oidc_skip_issuer_verification` setting is required to disable following checks:
* Startup check for matching issuer URL returned from [discovery document](https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration) with `oidc_issuer_url` setting. Required, as document's `issuer` field doesn't equal to `https://login.microsoftonline.com/common/v2.0`. See [OIDC Discovery 4.3](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfigurationValidation).
* Matching ID token's `issuer` claim with `oidc_issuer_url` setting during ID token validation. Required to support tokens issued by different tenants. See [OIDC Core 3.1.3.7](https://openid.net/specs/openid-connect-core-1_0.html#IDTokenValidation).
To provide additional security, Entra ID provider performs check on the ID token's `issuer` claim to match the `https://login.microsoftonline.com/{tenant-id}/v2.0` template.
`insecure_oidc_skip_issuer_verification` is required because tokens are issued by tenant-specific issuers such as `https://login.microsoftonline.com/<tenant-id>/v2.0`, while the configured discovery URL is `common`.
### Workload Identity
Provider supports authentication with federated token, without need of using client secret. Following conditions have to be met:
:::warning
When issuer verification is disabled for a multi-tenant app, set `entra_id_allowed_tenants` unless you intentionally allow users from any tenant. Treat the allowed tenant list as the trust boundary for multi-tenant deployments.
:::
OAuth2 Proxy still validates that the token issuer follows the expected Microsoft Entra issuer format. `entra_id_allowed_tenants` then restricts which tenant IDs are accepted. Use tenant IDs rather than tenant domains. The tenant ID for personal Microsoft accounts is `9188040d-6c67-4c5b-b112-36a304b66dad`.
```toml
entra_id_allowed_tenants = [
"9188040d-6c67-4c5b-b112-36a304b66dad",
"<your-tenant-id>"
]
```
## Workload Identity
OAuth2 Proxy can authenticate to Entra ID with a federated token instead of a client secret. This is commonly used with [Azure Workload Identity](https://azure.github.io/azure-workload-identity/docs/) on AKS or other Kubernetes clusters.
Checklist:
- The cluster has a public OIDC issuer URL.
- The Azure Workload Identity admission webhook is installed or enabled.
- The app registration has a federated identity credential whose subject exactly matches the OAuth2 Proxy service account: `system:serviceaccount:<namespace>:<service-account>`.
- The OAuth2 Proxy Kubernetes service account is annotated with `azure.workload.identity/client-id: <app-registration-client-id>`.
- On AKS, also set `azure.workload.identity/tenant-id: <tenant-id>` when your setup requires it.
- The OAuth2 Proxy pod is labeled with `azure.workload.identity/use: "true"`.
- OAuth2 Proxy is configured with `entra_id_federated_token_auth=true`.
- `client_secret` is omitted.
- The admission webhook injects `AZURE_FEDERATED_TOKEN_FILE`; OAuth2 Proxy validates this variable at startup when federated token auth is enabled.
* Cluster has public OIDC provider URL. For major cloud providers, it can be enabled with a single flag, for example for [Azure Kubernetes Service deployed with Terraform](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/kubernetes_cluster), it's `oidc_issuer_enabled`.
* Workload Identity admission webhook is deployed on the cluster. For AKS, it can be enabled with a flag (`workload_identity_enabled` in Terraform resource), for clusters outside of Azure, it can be installed from [helm chart](https://github.com/Azure/azure-workload-identity).
* Appropriate federated credential is added to application registration.

### Single tenant without groups
See: [Azure Workload Identity documentation](https://azure.github.io/azure-workload-identity/docs/).
### Example configurations
Single-tenant app without groups (*groups claim* not enabled). Consider using generic OIDC provider:
```toml

oidc_issuer_url = "https://login.microsoftonline.com/<tenant-id>/v2.0"
client_id = "<client-id>"
client_secret = "<client-secret>"
scope = "openid"
```
Single-tenant app with up to 200 groups (*groups claim* enabled). Consider using generic OIDC provider:
### Single tenant with groups in the token

allowed_groups = ["968b4844-d5e7-4e18-a834-59927959369f"]
```
Single-tenant app with more than 200 groups and workload identity enabled:
### Single tenant with group overage and Workload Identity

allowed_groups = ["968b4844-d5e7-4e18-a834-59927959369f"]
entra_id_federated_token_auth = true
```
Multi-tenant app with Microsoft personal accounts & one Entra tenant allowed, with group overage considered:
### Multi-tenant with one Entra tenant and personal Microsoft accounts allowed
```toml

]
email_domains = ["*"]
```
## Kubernetes Dashboard Integration
### AlphaConfig provider example
For a complete guide on integrating oauth2-proxy with Kubernetes Dashboard on AKS using Azure Entra ID authentication, including detailed configuration examples, RBAC setup, troubleshooting, and Workload Identity setup, see the [Kubernetes Dashboard integration guide](../integrations/kubernetes-dashboard.md).
```yaml
providers:
- id: entra
provider: entra-id
clientID: <client-id>
clientSecret: <client-secret>
oidcConfig:
issuerURL: https://login.microsoftonline.com/<tenant-id>/v2.0
emailClaim: email
groupsClaim: groups
userIDClaim: oid
scope: openid
allowedGroups:
- ac51800c-2679-4ecb-8130-636380a3b491
```
## Troubleshooting
| Symptom | Likely cause | Fix |
| ------- | ------------ | --- |
| Users from unexpected tenants can sign in | Multi-tenant issuer is configured without `entra_id_allowed_tenants` | Add an allowed tenant list or use a tenant-specific issuer for single-tenant apps. |
| Users with many groups fail `allowed_groups` | Group overage occurred but Graph permission or consent is missing | Add Microsoft Graph delegated `User.Read`, include it in `scope` if it must be requested during sign-in, and grant consent as required. |
| `allowed_groups` never matches | Display names were used instead of object IDs, or groups claim is not enabled | Enable groups claim and configure `allowed_groups` with Entra group object IDs. |
| Cookie or header size errors | ID token contains many groups or claims | Use Redis session storage and limit emitted claims where possible. |
| Workload Identity startup validation fails | `AZURE_FEDERATED_TOKEN_FILE` was not injected or is unreadable | Verify service account annotations, pod label, webhook installation, and federated credential subject. |

See also [our local testing environment](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/local-environment) for a self-contained example using Docker and etcd as storage for Dex.
#### Amazon Cognito user pools
Amazon Cognito user pools are OIDC-compatible and can be configured with the generic `oidc` provider.
Create a Cognito user pool app client for a server-side web application:
- Enable the authorization code grant.
- Configure the OAuth2 Proxy callback URL, for example `https://oauth2-proxy.example.com/oauth2/callback`.
- Use a confidential app client with a client secret; OAuth2 Proxy requires `client_secret` or `client_secret_file` for the generic OIDC provider.
- Request the scopes your app needs, commonly `openid`, `email`, and `profile`.
Example configuration:
```toml
provider = "oidc"
provider_display_name = "Amazon Cognito"
oidc_issuer_url = "https://cognito-idp.<region>.amazonaws.com/<user-pool-id>"
redirect_url = "https://oauth2-proxy.example.com/oauth2/callback"
client_id = "<app-client-id>"
client_secret = "<app-client-secret>"
scope = "openid email profile"
email_domains = ["*"]
```
##### EKS workload identity and Cognito client secrets
AWS has workload identity features for Kubernetes, including [IAM roles for service accounts (IRSA)](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html) and [EKS Pod Identity](https://docs.aws.amazon.com/eks/latest/userguide/pod-identities.html). They let a pod obtain AWS IAM credentials for AWS API calls without storing AWS access keys.
These features are not the same as Microsoft Entra ID Workload Identity client authentication. OAuth2 Proxy's `entra-id` provider can exchange the authorization code at the token endpoint with a projected Kubernetes service account token instead of a client secret. Amazon Cognito user pool app clients do not provide an equivalent OAuth2 token endpoint flow for OAuth2 Proxy to replace `client_secret` with IRSA or EKS Pod Identity credentials.
For Cognito-backed OAuth2 Proxy deployments on EKS:
- use `client_secret_file` with a Kubernetes Secret or an external secret sync mechanism if you need secret rotation,
- use IRSA or EKS Pod Identity only for separate AWS API access by the pod,
- do not expect IRSA or EKS Pod Identity to authenticate OAuth2 Proxy as a Cognito app client.
