Hello SharePoint Community!
I'm new here and I have a very important question.
We are using SharePoint Server 2007 in our Company. All Clients run with Vista or XP and have installed Office 2007. These clients are inside our windows domain and the users sign on into the domain too. The SharePoint Website Collection is placed in the Intranet-Zone in the Internet Explorer (IE8).
With this Configuration Single Sign On should be working! And when the Users start IE and go to the Portal-Site all works fine, there is no additionally authentication avalible! But some Users have the following problem:
Single Sign On works without any problems, when users surf to the Portal-Site with Internet Explorer. But the first time the Users open an Office document from a library, an authentication prompt comes up and the users have to enter their user credentials. After this additionally authentication, there is no authentication problem when the user open other documents.
Have anyone an idea?
Thanks a Lot! Austin
