Logging in works fine, and I can specify an "ldap_access_filter" to limit the
people who can log into the machine by the AD groups they are in and it works a treat.
The problem I have is: when I log in I can not see the secondary groups that my userid
is in. When I run "id" or "groups", I only see my primary group:
[tim@rhel6 ~]$ groups
If I run the "groups" command on a RHEL5 system (using ldap/krb5/pam_ldap), you
see many groups:
Can you send the sanitized ldap.conf you use for pam_ldap and the log
output of sssd during the 'groups' call with 'enumerate = false' (see
[tim@rhel5 ~]$ groups

I've been through the red hat bugzilla and sssd trac and I don't see a solution.
I have set my schema to
"rfc2307bis"<https://bugzilla.redhat.com/show_bug.cgi?id=580402> and I
have enumerate = true<https://bugzilla.redhat.com/show_bug.cgi?id=626775>
I'm wondering if sssd only grabs the first 1000 users and 1000 groups and then
[root@rhel6 /]# grep 1000 /var/log/sssd/sssd_KRB5DOMAIN.log
(Tue Dec 21 14:50:11 2010) [sssd[be[KRB5DOMAIN]]] [sdap_get_users_process] (6): Search
for users, returned 1000 results.
(Tue Dec 21 14:50:17 2010) [sssd[be[KRB5DOMAIN]]] [sdap_get_users_done] (9): Saving 1000
Users - Done
(Tue Dec 21 14:50:21 2010) [sssd[be[KRB5DOMAIN]]] [sdap_get_groups_process] (6): Search

(Tue Dec 21 14:50:36 2010) [sssd[be[KRB5DOMAIN]]] [sdap_get_groups_done] (9): Saving 1000

[root@rhel6 ~]# getent group | wc -l
[root@rhel6 ~]# wc -l /etc/group
Could it be because our AD has many more than 1000 users and 1000 groups? If so, if
there any way to increase this limit?
AD only sends 1000 entries at a time. This is called paging and we plan
to support paging with sssd 1.6 (see trac ticket #658). With this large
amount of users and groups I would recommend to set 'enumerate = false',
because for most of the typical uses cases this should be sufficient.
Alternatively, if we there was a group search filter option that would also reduce the
number of groups to enumerate, but I see this feature has already been
I'm not convinced this 1000 record limit exists or is even the root cause of my
problem though. If there's anything you guys can suggest I'd be most
