  | Looked at both of these before posting, groupmod lets you change group
  | names and group id's and not add users to groups,

 on my SUSE 9.1 box `groupmod -A USER GROUP' is documented
 as adding USER to GROUP.  but I did not see this option on
 Ubuntu 7.10, where `gpasswd' looks like the command to use.

 you should not be using `useradd/ on an existing user!
 you should only run it once, to create a new user.
 that is, you specify, using `-G ...', the groups you want
 the new user to be in.  (it is clearly possible there's
 another Ubuntu/SUSE difference here; I didn't check?)

 as a point of interest, this command does not seem to
 exist on SUSE 9.1, albeit it does on Ubuntu 7.10; i.e.,
 another distro/version/something difference here.
 ( as a Wild Guess, and keeping in mind the age of
  SUSE 9.1, I'd guess these differences are a LSB
  issue; i.e., Ubuntu follows the LSB whilst the SUSE
  in question is "too old". )

cheers!
