Mark,

Thanks for the info.  I've got 6 or more active computers using the low 
range UIDs (>=500), plus the file server, plus countless backups and one 
new distribution that using the higher range UIDs (>=1000).  So my clear 
preference would be to coax Ubuntu to follow the existing plan.  And I'm 
partially there.  My existing users can use Ubuntu with their existing 
UID.  There are a few residual programs that must get the UID range from 
something other the adduser.conf file.  The login screen refuses to list 
my users, though it sees the high range one it created.  Likewise the 
GUI admin tool to modify users & groups doesn't see my users in the 
lower range.  There may be other programs too. 

When I run low on more important tasks, I may try to chase this one 
down.  I just hoped someone on this list might have an easy answer.  I 
really haven't researched it yet.

-Jamie
