I have a TFS 2010 test installation on a Windows Server 2008 Enterprise SP2. While confguring the TFS the SharePoint Services 3.0 were installed. So far all seems to work fine, I can create team project collections and I get a SharePoint site for them. As
the "Administrator" user who installed the TFS I even can create team projects with the associated SharePoint sites.
My problem is, that if another (local) user who is member of the TFS group "Project Collection Administrators" creates a team project, I get the error "TF218017: A SharePoint site could not be created for use as the team project portal. The
following error occurred: TF250044: A SharePoint site cannot be created at the following location: http://<Sharepoint site address>. The following user does not have the required permissions in SharePoint to create a site at that location: <user name>
I added the user to the "Service Accounts for SharePoint Web Application" in the Team Foundation Server Administration Console. I added the user as well to the SharePoint Farm Administrator group, to the "Site Collection Administrators"
and to the site collection administrators in "Application Management" as the second administrator (all I could do so far) in SharePoint. The result was the same: Still not enough rights.
I am running out of ideas. What could possibly be the source of this problem?
