I download and installed the SSOPortal IIS application and integrated it into a Sharepoint page using a Page Viewer webpart. I get the SSOPortal from the
Live@edu page and I think its this codeplex project.
I am experiencing a double logon and even having my users loged on Sharepoint, the first time the SSOPortal is called, an explorer/windows logon page appears.
I suspect this is something related to setup but I don't know where to look for... Sharepoint, IIS or ISA server configuration. Any idea on where to start looking?
