Hi Shobha,
As you rightly mentioned SAML is not supported with RFC/SAP GUI. AFAIK below are the authentication mechanisms supported for Agentry Applications (client authentication) in SMP 3.0
1. Basic Authentication (below are the possible authentication providers)
a. http/https authentication
b. Directory Service LDAP/AD
c. No Authentication Challenge
2. Network Edge token based SSO (below are the possible authentication providers)
a. Populate JAAS Subject from Client
b. http/https authentication
3. SSO mechanism only basic authentication is supported
4. Kerberos SSO Any authentication provider (need to confirm I have not tried it)
I would also like to take inputs from Bill Froelich (@bill can you please provide some comments and correct me if I am wrong and help Shobha)
Regards
Murali
