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.

# getent passwd 1744
orion:*:1744:1001:Orion Poplawski:/home/orion:/bin/bash

Everything else seems to resolve the uid fine.

Version-Release number of selected component (if applicable):
quota-3.17-16.el6.x86_64   

This can be resolved by setting:

enumerate = true

in /etc/sssd/sssd.conf for the domain.  But instead of walking through the password entries with getpwent(), I think it would be better to use getpwuid().  Similar with groups.

Comment 2 Petr Pisar 2012-10-26 13:35:35 UTC 
Indeed walking whole user database is pointless. (Though there can be some corner cases when it's faster than querying for each ID directly. E.g. if disk quotas list a lot of IDs that are missing entry in user database. But then there is `-n' option.)
Comment 3 Petr Pisar 2014-10-21 12:19:38 UTC 
As stated by upstream:

> XFS, ocfs2, or ext4 (just recently) do not have quota files available to
> userspace applications and thus repquota has to be implemented by iterating
> over all users and querying kernel for quota information. So for those
> filesystems we have to use getpwent().

Changing the quota in a way you request would break another use cases. Therefore I will postpone resolution of this issue to the upstream.
