The history of SAML support in CAS clients is quite confusing. It started
out as a way to implement attribute release with an eye to full protocol
compliance, but little beyond the attribute release got implemented.
There's no CAS client that supports SAML signature validation, and I have
no idea whether there are additional limitations that would break them.

The good news is that the CAS protocol support in v3 does support the
"CAS-flavored SAML 1.1" support found in many clients. We use that
copiously at my home institution.
