You need to understand how Security Assertion Markup Language authentication (SAML) works or you have one of the following questions:
WSS implementing SAML Authentication.
For these examples, we use the Auth Connector Software as the SAML IDP (the BCCA-as-IDP feature).
For Web Security Service, SAML user authentication is currently available for the Explicit Proxy and IPsec/VPN access methods.
SAML allows for "promptless" user authentication.
Please understand that SAML is a complex protocol, that requires at least seven (7) request/response transactions for every URL (including for every image and object on a page).
