Virtual Users with SAML in WebLogic

A small blogpost how you can use virtual users on your SAML Service Provider WebLogic Server. A virtual user is a user who is authenticated on the SAML Identity Provider and this user is transfered ( with all his attributes and roles )  in a SAML Token to the Service Provider, this user does not need to exists on the WebLogic server of the Service Provider.
Before you can use this feature you need to setup SAML 2.0 SSO on your WebLogic Domain. You can follow this blogpost for all the instructions. You can also do this with Web Services but then you need to follow this guide.

First we need to enable Generate Attributes on the Identity Provider Side.
Go to the myrealm security realm ->  Providers -> Credentials Mapping -> your SAML 2.0 Credential Mapping Provider -> Provider Specific.
Also do this on the imported Service Provider Partner located at the Management tab of your SAML 2.0 Credential Mapping Provider. Open the Service Provider Partner and also enable here Generate Attributes.

Next step is to configure the SAML Service Provider.
Go to the myrealm security realm ->  Providers ->  Authentication -> your SAML 2.0 Identity Assertion Provider -> Management Tab.
Open your imported Identity Provider Partner configuration.
Enable Virtual User and also enable Process Attributes.

Now we need to add an extra WebLogic SAML Authentication Provider. This provider will process the virtual user SAML token with all its attributes and roles.
Set the Control Flag to Sufficient also change the other authentication provider from Required to Sufficient.
