The Code tab in a Team Project's TFS web portal allows users to check in/out items. Is there a way other than assigning users to the Stakeholder access level to prevent them from being able to check things in via the Web Portal if they have the permissions to actually check into a Team Project? It seems like you cannot explicitly exclude the Code tab form the Default or Advanced access levels, nor can you define a custom access level.
Our issue with the check in of an item from the Web Portal is that it does not evaluate any check in polices, nor can you associate the object you are checking in with a Work Item. We to want enforce developers using only Visual Studio to check in items into source control.
