useradd: Unknown group `dialout'.

[GnanaShekar]

Hi,

I am getting the following error while creating a local unix user account. Please suggest.

bngddem3:~ # useradd -m -d /home/rrao -s /bin/bash -g pncerts rrao
useradd: Unknown group `dialout'.
useradd: Unknown group `uucp'.
useradd: Unknown group `video'.
useradd: Unknown group `audio'.
useradd: Unknown group `pncerts'.


bngddem3:~ # more /etc/SuSE-release
SUSE LINUX Enterprise Server 9 (x86_64)
VERSION = 9
PATCHLEVEL = 3

Thanks & Regards,

Does the group "pncerts" exist?
# grep pncerts /etc/group

If no you should add new group
# groupadd pncerts
and then add new user using your command useradd ...

Hi,

pncerts group exists.

bngddem3:~ # tail -f /etc/group
haclient:!:90:
radiusd:!:101:
quagga:!:102:
vscan:!:103:
nobody:x:65533:
nogroup:x:65534:nobody
users:x:100:jsingh,pmirji,vijay,venkat,pmallick,grajashe,sgummara
dump:!:104:
dba::1000:oracle
pncerts:!:1001:

Also, I am getting the error message even if I donot specify the "pncerts" group in the useradd command.

bngddem3:~ # useradd -m -d /home/rrao -s /bin/bash rrao
useradd: Unknown group `dialout'.
useradd: Unknown group `uucp'.
useradd: Unknown group `video'.
useradd: Unknown group `audio'.

Please suggest,

Check out "/etc/default/useradd" file also and remove the groups that do not exist.

[GnanaShekar]

Hi,

I am able to create a user (though it throws some errors) with the following command (without -g pncerts option).

bngddem3:~ # useradd -m -d /home/rrao -s /bin/bash rrao
useradd: Unknown group `dialout'.
useradd: Unknown group `uucp'.
useradd: Unknown group `video'.
useradd: Unknown group `audio'.

However while changing the password I get the following error message:

bngddem3:~ # passwd rrao
Changing password for rrao.
passwd: User not known to the underlying authentication module
bngddem3:~ #

I could get the following from the logs

Apr 7 20:33:30 bngddem3 useradd: new user: name=rrao, uid=1011, gid=100, home=/home/rrao, shell=/bin/bash
Apr 7 20:36:04 bngddem3 passwd[31183]: User root: User not known to the underlying authentication module

Also the contents of /etc/default/useradd is

bngddem3:~ # more /etc/default/useradd
GROUP=100
HOME=/home
INACTIVE=-1
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
GROUPS=dialout,uucp,video,audio

Please suggest.

As Sergejs said, remove the unwanted groups from the 'GROUPS' line in '/etc/defaults/useradd'.

This will stop 'useradd' trying to add the groups automatically when you add a new user, and stop the error from occuring.

Hi,

I have removed the "GROUPS" from /etc/default/useradd.

now I am able to create user:

bngddem3:/etc # useradd -m -g pncerts tmp3
bngddem3:/etc # passwd tmp3

gut getting the following error:

passwd: error while loading shared libraries: libuser.so.1: cannot open shared object file: No such file or directory

Please suggest,

[Stuart Browne]

Well the change you made shouldn't have any affect on the 'passwd' command, so what else have you done recently?

It looks like one of the libraries has dissapeared now.

[GnanaShekar]

Hi,

From the e-mail trace u can see that I was unable to change password earlier also.

bngddem3:~ # passwd rrao
Changing password for rrao.
passwd: User not known to the underlying authentication module
bngddem3:~ #

I found that the nsswitch.conf file was empty. I later on copied this file from a similar system.

now I am getting this error:

bngddem3:/etc # passwd tmp2
passwd: error while loading shared libraries: libuser.so.1: cannot open shared object file: No such file or directory

Please suggest,
Thanks & Regards,
