Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Doc Text:	Cause: SSSD downloaded the complete nested groups when looking up groups by SID, especially during tokenGroups processing when SSSD was configured with AD back end and disabled ID mapping Consequence: initgroups operation (and by extension "id" processing and logins) were taking too long Fix: Only information about the group itself and not its members is downloaded Result: Logins are and ID processing are faster now for setups with AD back end and disabled ID mapping.

Description Jakub Hrozek 2015-03-13 15:31:25 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2601

Currently SSSD downloads the complete nested groups when looking up groups by SID, especially during tokenGroups processing. We should only download the information about the group object itself, not the contents of the group
