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.

Description Noriko Hosoi 2014-04-11 19:26:01 UTC 
+++ This bug was initially created as a clone of Bug #1086901 +++

Description of problem:
If you do a bind, and there is an error before the sdn can be set in the pblock - e.g. invalid sasl mech, unknown sasl mech, invalid bind method, invalid ldap version, protocol/decoding errors with bind parameters or controls - the cleanup code will get the NULL sdn from the pblock rather than freeing the unset sdn variable.
Comment 2 Jenny Severance 2014-10-21 20:04:13 UTC 
To Verify (see RHEL 6.6 bug)

1. Run server via valgrind.
2. Run ldap command with ...
   e.g. invalid sasl mech, unknown sasl mech, invalid bind method, etc.
   which is supposed to faile.
3. stop the server and check there is no do_bind in the valgrind output.

I'm sorry, I was running valgrind without debuginfo package for 389-ds. 
I repeated the tests with debuginfo installed. No do_bind in the output.
