Redirection lost with CAS RP -> Choice -> SAML Discovery Protocol -> SAML IDP
When testing LL::NG 2.0 as CAS IDP, with a Choice to redirection on a SAML IDP (through Renater WAYF page), when redirected back from SAML IDP, we lost the CAS protocol context, and we are not redirected back CAS RP.
Maybe the issue is linked to the WAYF redirection.
