Our TFS 2010 install is used both by Business Analysts and our Developers. The Analysts only need access to SharePoint\ Reporting Services, not TFS Source control, so I created just such a record for them under TFS Admin. Then I successfully
committed the record but noted that the record immediately disappeared from the Admin tool. I re-created the same record, committed it again, and once again the record vanished fom the Admin tool. The History tab showed the record was indeed created so
something is odd.
I checked SharePoint and found the Analyst assignment I made was indeed present in SharePoint. Under Team Explorer I manually assigned the Analyst group "read" only permissions to the TFS site and the missing record now appeared under TFS Admin.
I think this is a bug in the product. Do you agree?
