git repository in single system user environment

in SVN it was possible to work in several peop开发者_JS百科le 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?

Git or any DVCS doesn't support a "centralized" authentication due to its distributed nature. I.e. you can sign each commit with any string you want.

The way I managed that in a common working tree was by defining an alias for git:
The alias was referring to a wrapper, which:

• asks for a username and email, and then set GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL, GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL.
• call the actual git executable with all the parameters initially passed to the wrapper.

From there, all git commands are done with the right credentials.
