"""This module deal with users and groups

On each connection we may need to map unames and gnames to uids and
gids, and possibly vice-versa.  So maintain a separate dictionary for
this.

On the destination connection only, if necessary have a separate
dictionary of mappings, which specify how to map users/groups on one
connection to the users/groups on the other.  The _user_map and _group_map
objects should only be used on the destination.
