Thanks Alexander.  Even though I'm not running sshd I added 'DenyUsers
newuser' just in case.

I changed the new user's shell like 'chsh -s /bin/bash' and I can now
log in in the terminal but not in gdm.  Logging in with gdm works fine
with my user.  Does anyone know what the problem might be there?

Yes, you can configure that in SSH. There are the 

DenyUsers
DenyGroups

keywords for sshd_config.

Hi Grant,

Googling with 'restricted shell' returns some hints:
1.rsh (restricted shell) - looks that it's rather easy exit from it;
2.rssh - works with openssh (allows scp, sftp, rdist, rsync, and cvs);
3. rbash or bash with --restricted IIRC option;
4. check "zsh -r" vaguely remember the syntax, check about festures.
HTH. Rumen

Apparently -s /sbin/nologin wasn't such a good idea since the user
then can't log in via GDM.  Makes sense.  I want the user to be able
to log in via GDM but not via ssh.  Is that configured in ssh?
