CAS attributes in wsfederation not being forwarded to CAS client - spring-security

Question

I am implementing an authentication system for a Tomcat web application that gets authenticated against ADFS using CAS. I am using unicon's CAS server with ADFS integration.
I have reached to the state where I can see that the required attributes reach the CAS server. But these attributes are not getting forwarded to the client. check the figure below:
In the above image, the attribute map is empty after authentication. Also, when the client application validates the ticket, the attribute map is empty. Ref picture below:
After getting authenticated, the attributes are visible in the logs, but they are not being loaded into attribute Map.
The deployerConfigContext.xml is as follows. The attributeRepository bean and allowed attributes property in serviceRegistryDao bean are the probably the main focus areas.

The rest of the at CAS server is same as in the sample implementation of unicon's CAS-server implementation here
I've tried a lot of combinations in the mentioned beans. Being new to Spring I could not understand how to load the credentials in the attributeMap. Kindly guide me in forwarding the attributes sent by CAS server during authentication to the client application.

Answer 1

It looks like the WsFederationCredentialsToPrincipalResolver only extracts the principal id from the collection of attributes received, and ignores other attributes. So you only get the identity attribute defined in your configuration. You could for the time being, connect that resolver to your attribute repository and have it consume and retrieve attributes from there.
Note that CAS 4.2 supports and fixes this behavior and has built-in support for the ADFS integration. Your other option would be to extend WsFederationCredentialsToPrincipalResolver and have it process attributes and stuff them into the final principal created there by overriding the appropriate method.
