You're looking for userid mapping, handled by idmapd.

Your best long-term solution is to make the userids consistent
across machines by making a decision about who will be 1000, 
1001 and 1002, and then changing /etc/passwd and running
suitable "chown -R" commands, probably followed by find
commands.

Debian automatically starts user numbering at 1000, so it's a
good idea to have a consistent install username, if you can
arrange it.
