Identity provider configuration

The Onegini Token Server has no user management. The Onegini Token Server depends on external identity providers (IdP) to identify a user. The Onegini Token Server supports multiple integrations with identity providers out of the box. Custom integrations are also supported.

Go to Configuration and then to Identity providers to configure identity providers in the admin console.

General configuration

Add IdP

The following properties can be set for each type of identity provider:

  • Type: the type of this identity provider. The type can only be changed later from a generic SAML to a Onegini CIM identity provider.
  • Identifier: the id of the identity provider. This uniquely identifies the IdP and cannot be changed later.
  • Name: a human readable name of the identity provider. This name is not shown to the end user, only to administrators.
  • Default: an identity provider can be assigned to an application. When no identity provider is specified for an application, the default identity provider is used.
  • Enabled: flag to enable/disable this identity provider.

Additionally, for those identity providers that expose identity via API, it is possible make Onegini Token Server aware of this API. See Configure User Info endpoint for further details.

Configure a Onegini CIM Identity Provider

The Onegini CIM Identity Provider is meant to connect with the Onegini Consumer Identity Manager (CIM) IDP. It makes features like OpenID Connect easily configurable and exposes new features like App to Web SSO. It is configured in much the same way as a SAML Identity Provider.

Add Onegini CIM Idp

Depending on which integration(s) are enabled, the configuration requirements change. See the table below for information:

Field Example Required For Integration(s) Description
API Base Uri https://internal.example.com All The API base uri of the CIM IDP.
Public Base Uri https://public.example.com App To Web The public facing base uri of the CIM IDP (possibly the same as the API base uri).
Person API Username person_api_username User Info or App to Web The username of the Person API.
Person API Password password User Info or App to Web The password of the Person API.
Storage API Username storage_api_username Storage API The username of the Storage API.
Storage API Password password Storage API The password of the Storage API.
Configuration API Username configuration_api_username Configuration API The username of the Configuration API.
Configuration API Password password Configuration API The password of the Configuration API.

Configure a SAML Identity Provider

Add saml IdP

By default the endpoints required for SAML in the Onegini Token Server are disabled. These endpoints should be enabled via SAML Service Provider Configuration SAML Service Provider enabled to use the SAML IdP integration.

When the SAML IdP functionality is used the Onegini Token Server acts as a SAML service provider. The metadata of the service provider can be configured via SAML Service Provider Configuration. In the SAML IdP the Onegini Token Server has to be configured as service provider. Please refer to Configuring the Metadata of the SAML Service Provider for more information.

The Entity ID must be configured in the Onegini Token Server for a SAML IdP. The Entity ID in the configuration of Onegini Token Server should be equal to the Entity ID in the metadata of the IdP.

There are two options to specify the IdP metadata:

  1. 'Dynamic via URI' - the metadata is automatically fetched from provided url - typically Saml Identity Provider. This is the recommended option as the refresh of the metadata is handled automatically.
  2. 'Static XML' - the complete XML representing Saml metadata is provided directly as a static text. When using this option make sure that metadata has sufficient expiry date and keys within the metadata are up-to-date.

The Onegini Token Server supports multiple certificates in the metadata in order to migrate to a new certificate smoothly.

The Onegini Token Server supports IdP initiated SAML Single Logout (SLO). By enabling SLO, the IdP is able to terminate sessions at the Onegini Token Server. This means that when a user logs out at the identity provider, the Onegini Token Server will receive a request to revoke all access tokens and grants associated with that session. This feature is only available for web clients that do not make use of refresh tokens.

The Onegini Token Server can choose requested authentication context class reference which then will be used with all SAML requests. If none is specified it defaults to urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport

The SAML Authentication context comparison tells the identity provider how should it compare the requested authentication context to supported ones.

Note: The SLO enabled checkbox is available in the form if and only the SAML Service Provider Configuration SLO enabled is enabled.

By default only the user id of the user is mapped based on the name id available in the SAML assertion. By adding an attribute mapping more user attributes from the SAML assertion can be used. When creating an attribute mapping both the Name or FriendlyName of a SAML attribute can be used. Example:

SAML attribute mapping

The Onegini Token Server supports free format attribute names. All attributes (including the non default ones) are available in the token introspection response and in the consent template. A set of default attributes is available that can lead to different behavior in the Onegini Token Server:

  • userId
  • authenticationLevel
  • firstName
  • lastName
  • email
  • phoneNumber
  • languageCode

Configure a Header Identity Provider

When using the header IdP, the identity of the end-user must be provided via HTTP-headers to the Onegini Token Server. The headers must be set by a trusted entity in the network. For example a WebSEAL instance or another kind of reverse proxy. This entity is responsible for stripping headers which are set by untrusted parties (e.g. coming from the internet).

Headers can be mapped to user attributes based on the configured attribute mapping. A default attribute mapping is available out of the box. Only mappings that differ from the default mapping have to be configured. A non standard user attribute can also be defined using an attribute mapping.

Default mapping:

User attribute Header Description
userId userId The identifier of the user
authenticationLevel authenticationLevel A value indicating the authentication level of the user, this value is free format and should be interpreted by external systems
firstName firstName First name of the user
lastName lastName Last name of the user
email email The email address of the user
phoneNumber phoneNumber The phone number of the user
localeCode languageCode The locale of the user, used to localize the pages served by the Onegini Token Server.

A language code can also be provided via a cookie value. When the cookie is specified it will overrule the language code set in the header. The cookie name used for to overrule the language code header and the default language code can be set via the following Docker Compose environment variables.

Configure a Two way OTP Identity Provider

A Two way One Time Password (OTP) IdP generates two random strings. The first one is generated in the session on the mobile device. A second one is generated when the users starts a new session on a system that knows the identity of the user, for example a self service environment. An api is available for this system to interact with the Onegini Token Server. By entering the generated values in the different sessions a user can be linked to a mobile device.

A description on how to configure the access to the api can be found in the API configuration topic.

Optionally a scope validation service can be used to verify that a user has access to the requested scopes. A scope validation service can be configured via Docker Compose environment variables. This is only the first step of enabling scope validation services. For the second part of the scope validation configuration see the scopes topic.

Attribute mappings are not used in this IdP.

A user has limited time to complete the identification process using the two way otp IdP. When this time has exceeded the user is presented with the failure without recovery (dead end) page The process uses a cookie to identify the authentication transaction. The authentication transactions are kept in memory on the server side for a limited amount of time. The amount of time the transaction exists server side (and the cookie expiry time) can be configured via the User authentication session TTL property.

Configure an OAuth Identity Provider

Add OAuth IdP

The Onegini Token Server can act as an OAuth client for an identity provider that acts as an OAuth authorization server. The Onegini Token Server then uses the OAuth authorization code flow to obtain an access token and uses that access token to get user information.

The following properties can or must be set for the OAuth Identity Provider:

Property Example Required Description
Client ID jeguighreuwih8792459​uht893​ Yes The identifier for the Onegini Token Server in the OAuth IdP.
Secret fjerfr9uf089rf908f90​refeef​ Yes The secret for the Onegini Token Server in the OAuth IdP.
Authorization URL https://example.com/oauth/authorize Yes URL to start the authorization without request parameters. These are added by the Onegini Token Server.
Token URL https://example.com/oauth/token Yes URL to exchange the access grant for an access token without request parameters. These are added by the Onegini Token Server. The URL is called via HTTP POST. The client id and secret are sent via the HTTP Authorization header (Basic authentication) or via the url encoded form.
Profile URL https://example.com/me Yes URL for an OAuth resource call that returns a user profile. The URL is called via HTTP POST. The access token is sent via the HTTP Authorization header with a Bearer token.
Scopes profile No Scopes that are needed for getting the user profile. Multiple scopes must be separated by a space. An empty value is allowed.

The host, protocol and context are taken from a Docker Compose environment variable TOKEN_SERVER_COMMON_ENGINE_BASE_URI and must denote the public hostname on which the Onegini Token Server instance can be reached from the internet. The context root of the Onegini Token Server engine can optionally be set via Docker Compose environment variable: TOKEN_SERVER_COMMON_ENGINE_CONTEXT_ROOT.

During the OAuth authorization flow the user is redirected back from the OAuth IdP to the Onegini Token Server. This redirect URL is the engine base URI + the engine context root + /oauth-idp/callback. Example: https://token-server.example.com/oauth/oauth-idp/callback.

Attribute mappings are currently not supported in this IdP. The Onegini Token Server expects the profile in the following structure to extract the user identifier:

{
  "userId" : "user-1234"
}

Configure a custom Identity Provider

Note: the custom identity provider is deprecated in favor of the custom API identity provider and will be removed in a future release.

For a custom IdP only general IdP properties can be set via the Onegini Token Server admin console. Other configuration must be set as described in the documentation of this custom identity provider.

The type of the custom IdP is set by specifying its Spring bean name via a Docker Compose environment variable.

Configure a Two way OTP API Identity Provider

This identity provider gives nearly identical functionality to the browser based Two way OTP Identity Provider but uses an API approach. This is useful for the app developers as they can implement Two way OTP without using a browser and provide a more cohesive user experience.

For more information on the Identity Provider refer to the Two way OTP API topic guide.

Configure a Custom API Identity Provider

Custom API Identity Providers can be either One Step or Two Step. These Identity Providers utilize the Extension Engine to execute custom JavaScript to validate the registration. Scripts should be supplied when configuring this Identity Provider. Two Step requires an Init registration and Complete registration script while One Step only requires a Complete registration script. Both can have an optional script for Backchannel communication, but that is not required.

Add Custom API IdP

For more information on the Identity Provider refer to the Custom Registration topic guide.

See the Example Scripts for help creating the scripts.

Configure User Info endpoint

For any type of the Identity Provider it is possible to configure an endpoint which Onegini Token Server will use as a source of user identity attributes. It is used by Onegini Token Server to expose UserInfo and populate ID Token with claims in OpenID Connect flows. This endpoint needs to be compliant with Person API. The reference implementation of this API is provided by CIM. Refer to CIM documentation for API specification and instructions how to enable it.

  • Enabled: indicates whether identity attributes may be retrieved via API
  • Identity source URL: Url of the Person API compliant endpoint
  • Username: username that shall be used when accessing API
  • Password: password that shall be used when accessing API

The calls to the API are cached. The TTL of this cache can be configured as described in Cache Configuration

Attribute mapping

Add attribute mapping

Identity Provider attributes

Some identity providers are capable of providing user attributes during authorization. These attributes are associated with respective access tokens and are available as a key-value pair for an inspection via the Token introspection API.

By default, the attributes are stored under the original keys, but it is possible to override that behaviour by defining a custom mapping. If at least one custom mapping is defined, only those attributes will be mapped. That means other attributes that are not mapped will be dropped. If you are using SAML attribute name mapping in Onegini CIM, make sure to coordinate the configuration between the two products. The attribute names are case-sensitive.

A special user attribute is the user identifier. It identifies the user within the Onegini Token Server. For a SAML based identity provider the assertion Subject/NameID is the standard user identifier. Create an attribute that maps to userId if you need to use a different attribute as user identifier.

Person API attributes

The attributes are stored during authorization, but the Onegini Token Server will not resynchronize them later. This results in potentially stale data. To overcome this limitation, consider leveraging the Person API integration.

If the Person API integration is enabled, the Token introspection API returns all non-empty attributes from the Person API, in addition to the attributes that were returned during the authorization.

Supported attributes are:

  • first_name
  • last_name
  • gender
  • birth_date
  • locale
  • email
  • email_verified
  • phone_number
  • phone_number_verified
  • street_name
  • house_number
  • house_number_addition
  • city
  • region
  • country
  • postal_code

Similar to attributes provided by an identity provider, the names of attributes as returned by the Token Introspection API can be changed by defining a custom mapping. If at least one custom mapping is defined, only those attributes that are configured are mapped. Name of the attributes are case-sensitive.
