*** This bug is a security vulnerability ***
Public security bug reported:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.5 LTS
Release: 12.04
Codename: precise
$ dpkg -l sssd
ii sssd 1.8.6-0ubuntu0.3
System Security Services Daemon
Description of problem:
We changed one of the groups name in MSAD that was defined as Unix group from
uppercase to lowercase. After that we noticed problems with some of the
services. In sssd_nss.log we got error messages:
(Fri Oct 14 10:03:31 2011) [sssd[nss]] [nss_cmd_getgrgid_search] (0): getgrgid
call returned more than one result !?!
Problems:
1. Checking groups in domain resulted in this:
[root@SERVERNAME db]# getent group |grep -i gr
GROUPGROUP:*:10069:username
groupgroup:*:10069:username
2. Cache was not updated correctly even after we removed group from Domain and
added it again.
[root@SERVERNAME db]# getent group |grep -i gr
GROUPGROUP:*:10069:username
groupgroup:*:10113:username
We got expected result only after removing cache from /var/lib/sss/db
directory. Resetting service didn't help.
[root@SERVERNAME db]# getent group |grep -i gr
groupgroup:*:10113:username
This was fixed by developers of sssd and fix was merged to upstream:
https://git.fedorahosted.org/cgit/sssd.git/commit/?id=42fb63b478058d3eb9a483e640958bd63114d309
Would you, please, merge this fix to ubuntu's sssd precise version? Thanks.
