in SVN it was possible to work in several people on one working copy of a repository. SVN prompted for a username and password and commits were attributed to the user which logged in even though they accessed the server with one system user.
However, in git, I cannot find a way to acomplish this easily. I know the preffered workflow is to have a repository clone for each developer, but that is not possible in some cases.
Any ideas how to solve this?
