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.

Description James Ralston 2015-10-20 21:34:35 UTC 
Description of problem:

The %configure macro in the sssd.spec file for RHEL6 deliberately includes the --without-nfsv4-idmapd-plugin flag, which disables building the /usr/lib64/libnfsidmap/sss.so idmapd plugin. This makes it impossible for RHEL6 NFSv4 clients to leverage sssd to perform NFSv4 id mapping.

It contrast, the sssd.spec file for RHEL7 builds and packages the /usr/lib64/libnfsidmap/sss.so idmapd plugin, along with several other plugins that are excluded from the RHEL6 sssd packages.

We still have many RHEL6 clients that we need to configure as NFSv4 clients. We need the /usr/lib64/libnfsidmap/sss.so idmapd plugin.

I don't understand why the idmapd plugin (as well as other plugins) were excluded from the RHEL6 sssd packages. The reason can't be because they are too old to work effectively, because the latest RHEL6 sssd packages (1.12.2) are currently more recent than the latest RHEL7 sssd packages (1.12.4).

For now, we've rebuilt the sssd packages from source, patching the spec file to properly build and package the idmapd plugin. But we are highly disinterested in maintaining our own local fork of sssd for RHEL6. Please update the RHEL6 packages to include the idmapd plugin.

changes to spec file need to build idmapd plugin

Here are the (trivial) changes we made to the spec file in order to build the idmapd plugin.

If you do not want to maintain packages yourself than you can use back-ported version from Fedora 21 as a temporary solution.

Comment 5 Jakub Hrozek 2015-10-21 10:50:26 UTC 
Dev ack since this is just a specfile change.
Comment 6 Jakub Hrozek 2015-10-21 10:51:42 UTC 
I tried to find the reason we explicitly disable the plugin but couldn't...I suspect it's because we were trying to minimize the amount of new features added into 6.7 since it's already pretty late even in the RHEL cycle..
Comment 7 Jakub Hrozek 2015-10-28 19:03:54 UTC 
James, thanks for filing this bug. It's tentatively scheduled for 6.8.
Comment 8 James Ralston 2015-10-29 02:24:10 UTC 
Jakub: understood; thanks.

We don't have an issue with maintaining a local fork, as long as we know that we can eventually reintegrate with upstream.
Comment 9 Jakub Hrozek 2015-12-11 16:00:50 UTC 
FYI, here is a test repo: https://copr.fedoraproject.org/coprs/jhrozek/SSSD-6.8-preview/
Comment 11 Jakub Hrozek 2016-02-18 10:33:18 UTC 
To verify the bug, just make sure the sssd-common subpackage contains the sss.so file under libdir/libnfsidmap.

We don't test the functionality itself IIRC and moreover, it was tested by a user/customer who also reported a leak in the plugin. so we already know the plugin works :)
