The TFS Admin Tool allows a TFS administrator to quickly add users to all three platforms utilized by Team Foundation Server: Team Foundation Server, Sharepoint, and SQL Reporting Services, all through one common interface. The tool also allows administrators to change the current permissions on any of the three tiers, identify any errors, and view all of the users and their permission sets across Team Foundation Server, Sharepoint, and SQL Reporting Services.
