Stevan,
I know that CA has the ERP Agent, but I also know with newer versions of SAP that they have SAML 1.1 and 2.0 supoprt built in. Last I heard (about 18 months ago) there was talks about deprecating the SAP ERP Agent in favor of pushing people to SAML.
@ Shawn Sprague,
Being the Product Manager and someone I know has worked with the ERP Agnets, your insight here would probably be good to have.
