RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: sssd-1.8.0-5.el6
Doc Type: Bug Fix
Doc Text:
Cause: SSSD expects all users in a POSIX-enabled Active Directory group to be POSIX-enabled users. Consequence: If some members of a POSIX-enabled group were lacking the POSIX username attribute, SSSD would return an error when looking up that group. Fix: SSSD ignores non-POSIX group members. Result: SSSD will now return all POSIX-enabled group members and silently ignore non-POSIX members instead of failing the lookup and returning nothing.

Description Stephen Gallagher 2012-02-16 14:06:16 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1169

{{{
(Tue Jan 24 15:30:20 2012) [sssd[be[EXAMPLE.COM]]] [sysdb_search_users]
(0x0400): Search users with filter:
(&(objectclass=user)(originalDN=CN=U329266,OU=site,OU=Users,OU=Accounts,DC=example,DC=com))
(Tue Jan 24 15:30:20 2012) [sssd[be[EXAMPLE.COM]]] [sysdb_search_users]
(0x0400): No such entry
(Tue Jan 24 15:30:20 2012) [sssd[be[EXAMPLE.COM]]] [sysdb_attrs_primary_name]
(0x0020): Could not determine primary name: [22][Invalid argument]
(Tue Jan 24 15:30:20 2012) [sssd[be[EXAMPLE.COM]]]
[sdap_nested_group_populate_users] (0x0020): User entry 7 has no name attribute
}}}

In this case, we are talking to an Active Directory server that had some entries in its search filter that were missing the msSFU30Name attribute. When we were processing a group that contained this user, we would encounter the {{{"Could not determine primary name: [22][Invalid argument]"}}} error and fail. The proper behaviour should be to skip incomplete POSIX entries.
