You need to sign in to do that

SSO and Force.com Sites
Sites FAQ suggests that sites support single sign-on as there is seamless integration with Customer and PRM Portals, and Portals provide SSO capabilities.
What should be the end point URL for a SAML response when using sites, with a domain of e.g. test.sandboxname.cs1.force.com?
When we tried SSO to the partner portal with an endpoint of https://cs1.salesforce.com it all worked good and we were able to log into the partner portal. So that narrows the issue to the end point URL I believe.
Also, how do you change the Salesforce.com Login URL in the SSO settings once it's set? (Setup->Security Controls->Single Sign-On)
Thanks
