What is GridShib for Globus Toolkit?
GridShib for Globus Toolkit is a plugin for Globus Toolkit 4.0 (and later). GridShib for Globus Toolkit (GT) will consume X.509-bound SAML assertions issued by the GridShib CA or the GridShib SAML Tools. GridShib for GT will also issue SAML attribute queries to a Shibboleth Identity Provider with GridShib for Shibboleth installed. All of these SAML attributes are combined and used by the authorization framework to make local access control decisions.
