[keycloak-dev] backchannel logout for SAML SP

[Bill Burke]

I'm running into a problem implementing backchannel logout for our new 
SAML SP.  SAML has no way of transmitting client specific session 
information that I can tell.  So, I need some way of associating an 
auth-server specific session index and the Principal so that I can look 
up an Http Session and invalidate it based on one of those parameters.

We're gonna have the same exact problems when we implement the OIDC 
equivalent specifics (these are new BTW).

I'm thinking of writing a simple Infinispan cache that associates 
principals/session-indexes to http session ids and have it reusable 
between SAML and OIDC adapters.
