When the VCS client is on a Windows system, the system provides the credentials of the currently logged on Windows user by default when VCS commands are submitted if no other user credentials are defined. Therefore, if the user credentials for the Windows system are the same as those of a VCS user, that Windows user will be able to check files in to and out of the VCS server even if a VCS user has not been defined for that user.

For example, suppose you log on to Windows as user Pamela with a password of 1234X. You then log on to Designer as user Dev01 with a password of ABCD1. If you have a VCS user Pamela with a password of 1234X, you will be able to access the VCS repository even though your Integration Server user is not mapped to your VCS user. However, VCS Integration feature will have no Integration Server user to record in the VCS revision history transaction and will record only the VCS user.
