How to add user in linux

JATA01 · 10-18-2010, 02:40 AM

Hello Friends,

I want to add a user in a group, while doing so getting user doesn't exist. and when added this user getting user already exist message.

For reference find the below output.

[root@indls00x ~]# usermod -G Ind-Linux-QA mathurr
usermod: user mathurr does not exist
[root@indls00x ~]# /usr/bin/getent passwd | grep mathurr
mathurr:x:12271:12271:Mathur, Rajat X:/home/mathurr:/bin/bash
[root@indls00x ~]#

Thanks-
Shankar

Not sure it will work better, but have you tried with gpasswd?

gpasswd -a mathurr Ind-Linux-QA

Hope this helps you. On the other hand, I can not see why it does not work. I am curious if someone finds why.

[root@indls00x ~]# gpasswd -a mathurr Ind-Linux-QA
User doesn't exist.

This user is not in /etc/passwd file, when we add this user locally, getting user already exist.

Really strange.

Do you have something in /etc/shadow for that user?
Have you deleted this user? Maybe something went wrong, for instance the user could be connected when his account was deleted...

[root@indls00x ~]# gpasswd -a mathurr Ind-Linux-QA
gpasswd: unknown user mathurr

[root@indls0039 ~]# cat /etc/shadow | grep mathurr
[root@indls0039 ~]# ls -l /home
total 64
drwx------ 3 mathurr mathurr 4096 Oct 5 11:15 mathurr

Why don't you try

useradd mathurr
usermod -G Ind-Linux-QA mathurr

?

It won't delete any of the user's files (if he has any).

I have tried earlier and was in that case user is created locally in /etc/passwd file and geeting error at the time of login( user conflict)

I mean, when created user locally(useradd mathurr), getting conflicting user.

and when usermod -G Ind-Linux-QA mathurr, getting user does not exist, but getent passwd give the user details.

[root@indls00x ~]# usermod -G Ind-Linux-QA mathurr
usermod: user mathurr does not exist
[root@indls00x ~]# /usr/bin/getent passwd | grep mathurr
mathurr:x:12271:12271:Mathur, Rajat X:/home/mathurr:/bin/bash
[root@indls00x ~]#

Help is appreciated!!

If /usr/bin/getent passwd | grep mathurr returns a result, I guess there is something in /etc/passwd. This could be the reason of your problem.
What's the result of grep mathurr /etc/passwd ?

Nothing, even I have checked manually.

I am very sorry but I do not have other ideas to help you... :-(

I just got, it's a centrify user.

Now can we add users in a locally created group in "/etc/group"?
I am not sure, but can it be work?
