CAS 5.1.X - In Delegated authentication mode, 'service' is coming as null from the session

[Sanjay Semwal]

Hello there, 

I am using CAS 5.1.X, and facing this problem intermittently. Can you please suggest some solution?

In my case CAS is working as SP in delegated auth mode  and Azure is as IDP.  So when authentication is done on Azure, i get the SAML response. After that the control flow goes to CAS library class "DelegatedClientAuthenticationAction" where it tries to fetch "service" from the session,  which is coming as null object.

Here is the code fragment from DelegatedClientAuthenticationAction: - 

----------------------

// retrieve parameters from web session
final Service service = (Service) session.getAttribute(CasProtocolConstants.PARAMETER_SERVICE);
context.getFlowScope().put(CasProtocolConstants.PARAMETER_SERVICE, service);
LOGGER.debug("Retrieve service: [{}]", service);

--------

Any help would be appreciated on this. 

Thanks

To add bit more to it; intermittently I have been getting the issue related to redirection in delegated authentication mode in CAS version 5.1.x. Pls see popup message attached. 

I am observing it coming more frequently in chrome than any other browser.

Any help would be highly appreciated.

Thanks

Sanjay

Sanjay,

Version 5.1 is very old. It is difficult to know if this is a bug in that version of cas or if it is a browser problem.

Your best, and safest, option is to upgrade and see if the issue persists.
