Description Baptiste AGASSE 2013-08-09 04:54:23 EDT
Description of problem:

IPA v3.0 domain and sssd on EL6, some posix users in nested groups aren't showed in a "final" posix group, eg: user1, user2 are members of group1, user3, user4 are members of group2 and user5, group1 and group2 are members of group3, when i type "getent group" on a EL6 ipa client, group3 show only user5, user1 and user2 as member, when i log in with user 3 and i type "groups", group3 is not displayed. for another group, group4 (with group1 as nested group and group5 ), all users are displayed correctly.

After some others tests, it seems that "normal" (in opposition to posix) nested groups that are not expanded.

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

How reproducible:

Always for non posix nested groups

Steps to Reproduce:
1. choose a user and login on a IPA client box
2. type "groups" command a see if all groups are displayed
3. type "getent group" command and see if all users are displeyed in all groups

Actual results:

[user3@srv01 ~]$ groups
groupE groupA groupC groupB

Expected results:

[user3@srv01 ~]$ groups
group3 groupE groupA groupC groupB

Comment 2 Ondrej Kos 2013-08-16 09:03:51 EDT
Hello Baptiste,

I tried to reproduce the issue, configured IPA 3.0 and sssd 1.9.2-87.7, following user configuration:

group1: user1, user2
group2: user3, user4
group3: user5, group1, group2

[root@vm-178 ~]# getent group group1
[root@vm-178 ~]# getent group group2
[root@vm-178 ~]# getent group group3

[root@vm-178 ~]# id user1
uid=669200032(user1) gid=669200032(user1) groups=669200032(user1),669200028(group3),669200026(group1)
[root@vm-178 ~]# id user2
uid=669200033(user2) gid=669200033(user2) groups=669200033(user2),669200028(group3),669200026(group1)
[root@vm-178 ~]# id user3
uid=669200034(user3) gid=669200034(user3) groups=669200034(user3),669200028(group3),669200027(group2)

I am not able to reproduce your issue, could you provide your sssd.conf and LDIF for this case? If I understand this correctly, some of the groups are non-posix, but it's not clear from your report which ones.

Sorry for the delay, I was on vacation. since a diagram is worth a thousand words, in addition to the sssd's configuration, i've attached an users and groups diagram.
Comment 6 Ondrej Kos 2013-09-04 08:48:47 EDT
Hi Baptiste,

There are planned improvements in nested groups handling, in the meantime, is there some essential reason for you not to use posix group? Or as a workaround, you could create posix group which would mirror the non-posix group.
Comment 7 Baptiste AGASSE 2013-09-06 11:31:20 EDT
No essential reason, it's just some groups that only used in IPA in order to manage rights more easily. I will convert these groups to posix groups.
