Sometimes, group members may not be visible when running the getent group groupname command. This can be caused by an incorrect ldap_schema in the [domain/DOINNAME] section of the sssd.conf file. SSSD supports three LDAP schema types: RFC 2307, RFC 2307bis, and IPA. By default, SSSD uses the more common RFC 2307 schema. The difference between RFC 2307 and RFC 2307bis is the way which group membership is stored in the LDAP server. In an RFC 2307 server, group members are stored as the multi-valued memberuid attribute which contains the name of the users that are members. In an RFC2307bis server, group members are stored as the multi-valued attribute member (or sometimes uniqueMember) which contains the DN of the user or group that is a member of this group. RFC2307bis allows nested groups to be maintained as well.
When encountering this problem:
add ldap_schema = rfc2307bis in the sssd.conf file,
detele the /var/lib/sss/db/cache_DOMAINNAME.ldb file,
and restart SSSD.
If the workaround does not work, add ldap_group_member = uniqueMember in the sssd.conf file, delete the cache file and restart SSSD.

Description

where is this to be documented? This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. Currently the expectations have only been documented in the upstream FAQ document - https://fedorahosted.org/sssd/wiki/FAQ Would you prefer a better document such as the release notes? I don't think the man pages are a good place to include a low-level change like that. As discussed with Kaushik, the proper place seems to be the release notes, so I've set the flag. I cleaned up the FAQ, it was quite confusing. This is the link to the (hopefully correct now) upstream documentation: https://fedorahosted.org/sssd/wiki/FAQ#Idontseeanygroupmemberswhenrunninggetentgroupgroupname Marking as MODIFIED because the upstream documentation has been corrected. I'll leave the FixedIn field blank. Doc Text gives appropriate explanation and solution of the issue. Marking this bug verified. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. http://rhn.redhat.com/errata/RHSA-2013-0508.html |
