Entra ID: + +### ID Token (Recommended) +- Contains user/app identity claims +- Includes email, name, preferred_username +- Best for user authentication + +### Access Token +- Used for API authorization +- Contains app-only or delegated permissions +- Best for service principals and managed identities + +## Permissions + +The registry token issued after authentication includes: + +1. **Publish permission**: Always granted for the configured namespace pattern +2. **Edit permission**: Only granted if `ENTRA_ID_ALLOW_EDIT=true` + +## Troubleshooting + +### Token Validation Failed + +**Error**: `Invalid Entra ID token` + +**Solutions**: +- Verify the token is for the correct audience (client ID) +- Check that the token hasn't expired +- Ensure the tenant ID matches the configuration +- Verify the App Registration is configured correctly + +### Wrong Tenant + +**Error**: `token is from unexpected tenant` + +**Solutions**: +- Verify `ENTRA_ID_TENANT_ID` matches your Azure AD tenant +- Check that the user/service principal belongs to the correct tenant + +### Missing Claims + +**Error**: Claims not being extracted properly + +**Solutions**: +- Configure optional claims in App Registration → Token configuration +- Request an ID token instead of access token +- Check that scopes include `openid`, `profile`, `email` + +## Security Considerations + +1. **Token Storage**: Never commit tokens or client secrets to version control +2. **Token Expiration**: Tokens are short-lived; refresh them as needed +3. **Principle of Least Privilege**: Configure namespace patterns to limit what can be published +4. **Audit Logging**: Monitor authentication attempts and publishes +5. **Client Secret Rotation**: Regularly rotate client secrets +6. **Multi-factor Authentication**: Enable MFA for user accounts + +## API Reference + +### Endpoint + +``` +POST /v0/auth/entra-id +``` + +### Request + +```json +{ + "access_token": "eyJ0eXAiOiJKV1QiLCJhbGc..." +}
