SAML 1.1 and user type in SAP

Hi everyone,

I have two questions regarding SSO scenario in Netweaver 7.11:

1) Does Netweaver 7.11 support only SAML 1.1? or is SAML 2.0 also supported?

2) What SAP user types are allowed for such a scenario? Is it possible to create the user as Usertype "SYSTEM" in the backend along with SAML 1.1?

Thanks for your replies  in advance.
