Visual SourceSafe imposes project security by allowing you to assign project rights for individual commands for each user. Three rights commands are enabled on the Tools menu of Visual SourceSafe Administrator. You can choose a user in the user list for the database and assign rights using the Rights Assignments for User command. Alternatively, you can use the Rights by Project command to assign project rights. It is also possible to copy project rights from one user to another, using the Copy User Rights command. To use any of these commands, you must enable rights assignments using the SourceSafe Options dialog box from Visual SourceSafe Administrator
