Shibboleth and TMASystems

Brent,

We are expected to send the SAML response to a specific URL as in samlservice.aspx that will then consume the response.  From what I see in the documentation, the ACS URLs are virtual, not literal.  In our case, we are trying to send the response to a literal ACS URL.

I'm not sure how you're distinguishing between a "literal" URL and a "virtual" one, even with the example.  Maybe you're just referring to the query string?  There's no actual "file" at /Shibboleth.sso/ either.

Either way, from the IdP's perspective, the internal hosting architecture of the SP is opaque.  It just needs to know a trusted place to send the user back to with the assertion in hand.

For example instead of the ACS URL http://webtma.umaryland.edu/Shibboleth.sso/SAML2/POST, I need to send directly to http://webtma.umaryland.edu/tmalogin/samlservice.aspx?c=umb

Then that's the URL that should be in their metadata and in the AuthnRequest.  I believe the IdP will honor ACS URL's with query strings, but it's not a common use case, so this will be the first place to start looking should you have an issue.

Thanks,
Nate.
