diff src/director/user-directory.h @ 11321:5f350b5ff6d9 HEAD
Added initial implementation of a director process (for NFS users).
There are still some unimplemented features and bugs. Also changing mail
server list doesn't yet make sure that other directors won't assign the
same user to a different server at the same time.
