[SOLVED] useradd - user is different between red hat and suse

mikenash · 10-22-2015, 03:55 PM

I execute the following command on Red Hat Enterprise 7.1 and Suse Enterprise 12 and I receive different results.
useradd -m -d /home/Sam -k /etc/skel -g root -r -o -u 0 -s /bin/bash Sam
When issue whoami on Suse the output is Sam but on Red Hat the output is root!
Why is it not Sam?

It may be that you do not have the group root on the rhel system

You also specified uid 0 whih may cause an issue

You just created a duplicate of the root acct!!! DON'T do that - seriously.
If you have a user that needs root access either give them the root passwd or add them into sudoers.

I issued the command groups against both user ids on both systems and the results are the same. There is a group root and both user ids are in the group root. The same useradd command was issued on both systems. However, on Red Hat 7.1 I am logged in as root. Interesting and still investigating on the different results. Any explanation or suggestions?

I did investigate the -u 0 option which should be allowed with the -o option that allows for this.
-o, --non-unique
Allow the creation of a user account with a duplicate (non-unique) UID.

also rhel and suse use different starting places for the root id
500 VS. 1000

and DO NOT try to make a second root account under a different name

use "sudo "

i would bet that SELinux on rhel will through a temper tantrum if you do
