Has anyone written code to have the Alpha Five security system allow logins based on CAS (Central Authentication Service, http://www.jasig.org/cas), to enable single sign-on (SSO)? We do have logins working based on LDAP, but using CAS would let let our employees switch seamlessly between alpha applications and other intranet applications without having to re-enter their password. (We had been hoping to use SAML but sample client code for CAS seems to be more freely available.)
