Allow CAS app to participate in Shibboleth SLO

[mzico]

I tested in 4.1 ( with new 4.1.1 shibb patch ). Seems like SAML SLO is working perfectly but when we are initiating SLO from php app ( phpCAS, in this case ); it's not working.
Seems like CAS ticket ( which is issued by Shibboleth ) is still intact.

I have recorded a screencast which has three machines:

• https://test41saml.gluu.org [ my Gluu Server ]
• https://samlapp.gluu.org [ a shibboleth SP ]
• https://cas.gluu.org [ a cas app, phpCAS ]

Screencast: https://youtu.be/p6_pAu1a5LM

In this screencast, I tried:

• Login from SAML app, SSO good.
• Logout from SAML app, SSO good.
• Login from CAS app, SSO good
• Configured CAS app registration ( inside Gluu Server's "cas-protocol.xml.vm" ) so it can participate in Shibboleth SLO
• Tried Logout, not working. Session intact.

I am also attaching two logs:

• Successful SAML SLO
• Not successful CAS SLO.
• Note to check: issued ticket "ST-1584455312109-3FzcYp4ojdIw9BYxkAAE8vIHy" is also active in last section.

This should be assigned to Puja Sharma.

Got it, I sent invitation in SAML github group. After confirmation, we can reassign.

Re-adding log files, zip was bad before.

Just adding a note to self as I'll circle back to this.

This is probably not working because the relying-party.xml.template RP Configuration doesn't contain profile configuration for the CAS protocol. This should be added to allow CAS applications to Participate to Shibboleth SLO
