SSO can be configured via environment variables (shown below) or from the Settings UI after first boot.

## Google OIDC

1. Go to the [Google Cloud Console](https://console.cloud.google.com/apis/credentials)
2. Create a new **OAuth 2.0 Client ID** (Application type: Web application)
3. Add an **Authorized redirect URI**: `https://sencho.example.com/api/auth/sso/oidc/oidc_google/callback`
4. Copy the **Client ID** and **Client Secret**
5. Add to your `docker-compose.yml`:

```yaml
services:
  sencho:
    image: saelix/sencho:latest
    environment:
      - COMPOSE_DIR=/opt/compose
      - SSO_OIDC_GOOGLE_ENABLED=true
      - SSO_OIDC_GOOGLE_CLIENT_ID=your-client-id.apps.googleusercontent.com
      - SSO_OIDC_GOOGLE_CLIENT_SECRET=your-client-secret
      - SSO_CALLBACK_URL=https://sencho.example.com
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./sencho-data:/app/data
      - /opt/compose:/opt/compose
```

Restart Sencho. A "Google" button will appear on the login page.

## GitHub OAuth

1. Go to **GitHub > Settings > Developer Settings > [OAuth Apps](https://github.com/settings/developers)**
2. Click **New OAuth App**
3. Set:
   - **Application name**: Sencho
   - **Homepage URL**: `https://sencho.example.com`
   - **Authorization callback URL**: `https://sencho.example.com/api/auth/sso/oidc/oidc_github/callback`
4. Copy the **Client ID** and generate a **Client Secret**
5. Add to your `docker-compose.yml`:

```yaml
    environment:
      - SSO_OIDC_GITHUB_ENABLED=true
      - SSO_OIDC_GITHUB_CLIENT_ID=your-github-client-id
      - SSO_OIDC_GITHUB_CLIENT_SECRET=your-github-client-secret
      - SSO_CALLBACK_URL=https://sencho.example.com
```

## Okta OIDC

1. In the [Okta Admin Console](https://admin.okta.com), go to **Applications > Create App Integration**
2. Select **OIDC - OpenID Connect** and **Web Application**
3. Set the **Sign-in redirect URI** to: `https://sencho.example.com/api/auth/sso/oidc/oidc_okta/callback`
4. Note your **Okta domain** (e.g., `https://dev-123456.okta.com`)
5. Copy the **Client ID** and **Client Secret**
6. Add to your `docker-compose.yml`:

```yaml
    environment:
      - SSO_OIDC_OKTA_ENABLED=true
      - SSO_OIDC_OKTA_ISSUER_URL=https://dev-123456.okta.com
      - SSO_OIDC_OKTA_CLIENT_ID=your-okta-client-id
      - SSO_OIDC_OKTA_CLIENT_SECRET=your-okta-client-secret
      - SSO_CALLBACK_URL=https://sencho.example.com
```

## Custom OIDC (Keycloak, Authentik, Authelia, and others)

The Custom OIDC provider connects Sencho to any identity provider that supports OpenID Connect discovery. This includes Keycloak, Authentik, Authelia, Zitadel, KanIDM, Pocket ID, and any other spec-compliant provider.

1. In your identity provider, create a new **OIDC / OAuth2 client application**
2. Set the **Redirect URI** to: `https://sencho.example.com/api/auth/sso/oidc/oidc_custom/callback`
3. Note the **Issuer URL** (the base of the `/.well-known/openid-configuration` endpoint, without the well-known path)
4. Copy the **Client ID** and **Client Secret**
5. Add to your `docker-compose.yml`:

```yaml
    environment:
      - SSO_OIDC_CUSTOM_ENABLED=true
      - SSO_OIDC_CUSTOM_DISPLAY_NAME=Corporate SSO
      - SSO_OIDC_CUSTOM_ISSUER_URL=https://auth.example.com/realms/myrealm
      - SSO_OIDC_CUSTOM_CLIENT_ID=your-client-id
      - SSO_OIDC_CUSTOM_CLIENT_SECRET=your-client-secret
      - SSO_CALLBACK_URL=https://sencho.example.com
```

If your provider uses non-standard claim names, add claim mapping:

```yaml
    environment:
      - SSO_OIDC_CUSTOM_ID_CLAIM=sub
      - SSO_OIDC_CUSTOM_USERNAME_CLAIM=preferred_username
      - SSO_OIDC_CUSTOM_EMAIL_CLAIM=email
```

<Note>
  Most spec-compliant providers use the standard OIDC claim names (`sub`, `preferred_username`, `email`). You only need to configure claim mapping if your provider uses different names. See the [SSO feature page](/features/sso#provider-specific-setup-examples) for provider-specific notes.
</Note>

## LDAP / Active Directory

1. Identify your LDAP server's URL and port (default: `389` for LDAP, `636` for LDAPS)
2. Create a **read-only service account** (bind DN) that can search the user directory
3. Determine the **search base** (where users live in the directory tree)
4. Choose the right **search filter**:
   - OpenLDAP: `(uid={{username}})`
   - Active Directory: `(sAMAccountName={{username}})`
5. Optionally identify an **admin group DN** for role mapping
6. Add to your `docker-compose.yml`:

```yaml
    environment:
      - SSO_LDAP_ENABLED=true
      - SSO_LDAP_URL=ldap://ldap.example.com:389
      - SSO_LDAP_BIND_DN=cn=readonly,dc=example,dc=com
      - SSO_LDAP_BIND_PASSWORD=your-bind-password
      - SSO_LDAP_SEARCH_BASE=ou=users,dc=example,dc=com
      - SSO_LDAP_SEARCH_FILTER=(uid={{username}})
      - SSO_LDAP_ADMIN_GROUP_DN=cn=sencho-admins,ou=groups,dc=example,dc=com
      - SSO_LDAP_DEFAULT_ROLE=viewer
```

After starting Sencho, verify the connection in **Settings > SSO** using the **Test Connection** button.

<Warning>
  If your LDAP server is on the Docker host (not in a container), use the host's LAN IP or `host.docker.internal` (Docker Desktop) instead of `localhost`.
</Warning>

## Role mapping

By default, all SSO users are assigned the **Viewer** role. To grant Admin to specific users:

**For LDAP**: Set `SSO_LDAP_ADMIN_GROUP_DN` to the DN of your admin group. Users who are members of that group will be provisioned as Admin.

**For OIDC**: Set these two variables:

```yaml
    environment:
      - SSO_OIDC_ADMIN_CLAIM=groups
      - SSO_OIDC_ADMIN_CLAIM_VALUE=sencho-admins
```

This tells Sencho to check the `groups` claim in the OIDC ID token. If it contains `sencho-admins`, the user gets Admin. Roles are synced on every login, so removing a user from the admin group will demote them on their next sign-in.

<Note>
  Some providers (e.g., Okta, Zitadel) require custom scopes to include group claims in the ID token. You can configure additional scopes in the **Scopes** field in Settings > SSO, or via environment variable. The default is `openid email profile`.
</Note>
