Equivalencing usernames/ids across computers

[Tony van der Hoff <tony@vanderhoff.org>]

Not strictly a Debian question, but relates to Debian systems

I have a VPS, a laptop and a home server, with various users/ids on 
each, but with a degree of overlap. So, for example, on the VPS I have 
userA id 1001, userB id 1002, and userC id 1003, etc. On the laptop I 
have userA id 1001 and userC id 1002. On the home server, I have userA 
id 1002, userB id 1001, and userC id 1003. You get the picture.

This matters not, until I back up the laptop and desktop onto the VPS, 
at which stage confusion starts to arise. Backing up from the laptop to 
the desktop aggrevates the situation.

Of course I should have designed things better, and assigned the same 
user names and Ds to each; but things just grew.

So, apart from reallocating user names/numbers at this late stage, what 
dou you recommend using to map across the various systems without my 
having to think too hard about it?

Cheers,
