Here is my situation; we are developing a sharepoint portal that should be accessed from multiple different domains. And users from different domains should not enter their credentials. As far as i know, if the domains are trusted, then nothing to configure on sharepoint, we can choose people from different domains in People Picker, so it is ok.
But the domains i am talking about is not trusted but, i have been told that there is a federation service, (i think ADFS) in these domains.
So what can i do to make people from different domains to access the portal without entering username/password ?
Besides i dont know much about ADFS concept and ADFS-SharePoint relation?
Thanks in advance for any kind of information.
