su - root

[Fuad_1]

I have two users in different groups, and both have the root password. One can issue su - root and enter the system and the second one is not. Can any one explain this?

Do you have SU_ROOT_GROUP= set in /etc/default/security?

Hi,

No, i don't have it.

Hi,

What error messages are you seeing for the failed attempt? Is anything showing up in syslog?

Are both users using the same su command, check by giving the full path /usr/bin/su?

Is your system trusted, or using NIS? Is it only the root account that is affected?

regards,

Darren.

What OS release?

What was the last patch bundle installed?

What groups does user1 belong to that user2 does not?

What is the error message that user2 receives when they can't su to root?

The one that can login is in "users" group, and the one can not is in "ora" group. The message error is "su:sorry".

That sounds like they're entering the wrong password. Have you tried this yourself?

Hi Faud,

Have you checked the path to su command for both the users.

For each user, try

$type su

or

$which su

Hope this helps.

Hi Fuad,

long shot... but does the second user have an alias set up for the "su" command? I have tried to simulate the behaviour of your second user by setting up this alias:

# alias 'su'='su - jxk'

on a system where the user jxk exists. It could be that the second user had something similar to that.
