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: cyrus-sasl-2.1.26-20.el7_2
Doc Type: Bug Fix
Doc Text:
When using the Cyrus SASL library (cyrus-sasl) Generic Security Services API (GSSAPI) plug-in, all connections shared a single lock for both server and client implementations. As a consequence, a deadlock in the cyrus-sasl GSSAPI plug-in caused the whole Directory Server to become unresponsive when both outgoing replication and incoming client connections used SASL GSSAPI. This update introduces per-thread locks, which minimizes the required synchronization and prevents a deadlock from occurring if some threads are blocked. As a result, the Directory Server is now able to reliably handle concurrent connections that use the cyrus-sasl GSSAPI plug-in.
