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.

Fixed In Version: sssd-1.8.0-2.el6.beta2
Doc Type: Enhancement
Doc Text:
Cause: SSSD would maintain its connection to the LDAP server as long as possible, to avoid the overhead of reconnecting. Consequence: This could cause resource-limitation issues on the server, since SSSD clients would be tying up an available file descriptor. Change: SSSD now has a configurable idle timeout, after which it will disconnect from the LDAP server until the next request is received. Result: SSSD will be a less resource-intensive client for LDAP servers.

Description Ondrej Valousek 2011-10-07 12:59:27 UTC 
sssd should possibly not keep the connection to the LDAP server indefinitely as it could render the server to run out of resources.
Instead, we should close it after some (configurable) idle time.
