If you are going to have multiple users sharing a repository, generally they should be in the same group and the core.sharedrepository config option should be set (see "git help config", or the "shared" option to git-init).

I've never used that personally, though. I have always just used POSIX ACLs, with a default ACL on each directory giving access to everyone. E.g. (off the top of my head):

  for user in user1 user2 user3; do
    setfacl -R -m u:$user:rwX -m d:u:$user:rwX /path/to/repo
  done
