Description piotr.zawadzki 2012-12-11 10:21:32 UTC

Description of problem:

We use SSSD to configure authentication with Active Directory. When we run below set of commands using LOCAL account return code is 0:

[root@pl-krapdb02-q2 etc]# su - hmeuqi -c "false"
[root@pl-krapdb02-q2 etc]# echo $?
0

But when we stop SSSD and run the same set of commands the return code is 1 (CORRECT behaviour).

[root@pl-krapdb02-q2 etc]# service sssd stop
Stopping sssd:                                             [  OK  ]
[root@pl-krapdb02-q2 etc]# su - hmeuqi -c "false"
[root@pl-krapdb02-q2 etc]# echo $?
1

------------------

On the other hand, when SSSD is running but Active Directory account is used (not local like in the above example) the behavior is also correct:

[root@pl-krapdb02-q2 etc]# service sssd status
sssd (pid  14237) is running...
[root@pl-krapdb02-q2 etc]# su - pl32552 -c "false"
[root@pl-krapdb02-q2 etc]# echo $?
1

It suggests that the issue only occurs when local (not AD) account is used together with SSSD service.

Version-Release number of selected component (if applicable):

Red Hat Enterprise Linux Server release 6.3 (Santiago)
sssd-1.8.0-32.el6.x86_64

How reproducible:

[root@pl-krapdb02-q2 etc]# su - hmeuqi -c "false"
[root@pl-krapdb02-q2 etc]# echo $?
0

--------------

[root@pl-krapdb02-q2 etc]# service sssd stop
Stopping sssd:                                             [  OK  ]
[root@pl-krapdb02-q2 etc]# su - hmeuqi -c "false"
[root@pl-krapdb02-q2 etc]# echo $?
1

Steps to Reproduce:

Actual results:


Expected results:

Expected result is return code 1 instead of 0 when SSSD is used

Hi Piotr, can you check if the workaround with using pam_localuser (see https://bugzilla.redhat.com/show_bug.cgi?id=878030#c2) works for you?
