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.
DescriptionStephen Gallagher

Description of problem:
We are not properly handling the case where a group might have a memberuid attribute with no name (zero-length string). This causes a failure in the code that does not properly clean up after itself, resulting in SSSD holding open a transaction to the ldb, making it unable to cache new lookups properly (as data is only saved when all nested transactions are marked complete).
Version-Release number of selected component (if applicable):
sssd-1.5.1-20.el6
How reproducible:
Every time
Steps to Reproduce:
1. Create an LDAP group in RFC2307 with a memberuid attribute of zero length
2. Purge the cache and restart SSSD
3. run 'getent group <groupname>'
4. run 'getent passwd <valid user>'
Actual results:
Neither command returns results
Expected results:
The group request should ignore the empty name and return successfully. The user request should return the user properly.
