AW: Shibboleth as SAML Proxy

[Bergmann, Clemens]

Hi Nate,

thanks fort he insight. 
I am already in the process of configuring Shibboleth to remove CAS (Software) from the list and using the CAS (protocol) ability of Shibboleth. 
You are right. I Think I will split these two functions and do the (real) IdP part with shibboleth and the proxy part with simplesamlphp or SaToSa. The requrements for the later are still not that clear.

Mit freundlichen Grüßen
Clemens Bergmann
