the organization that i am currently working with are implementing
a scenario similar to what you described. essentially, a browser
client starts off (after portal authentication) with a
custom/app-specific security token which gets exchanged for a saml
1.1 sso token. that sso token then eventually gets exchanged for a
ws-security saml token. there is a "back channel" between a
business web service proxy and our saml-based security service.
this approach wasn't my call, i hasten to add. i just work there
;-)
they call their implementation "saml-based" but it is not strictly
saml-conformant. now that i have been exposed to their
non-conformant approach, i am fanatically interested in
understanding the conformant way to implement a saml solution
because i do not want my understanding of the specs shaped solely
by "the wrong way to do it" (if you know what i mean).
