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 Elio Maldonado Batiz 2010-10-15 23:34:22 UTC 
+++ This bug was initially created as a clone of Bug #642433 +++

Description of problem:
try any openldap command and use the LDAPTLS_CACERTDIR to pass in an arbitrary directory containing other directories.

It will abort as soon as openldap passes down a directory as a file.

It should probably, at most, return an error, if not ignore the entry completely.

This is the backtrace:

--- Additional comment from rcritten on 2010-10-12 18:06:02 EDT ---

In FileToItem() we call PR_GetOpenFileInfo() so I suppose we can just make sure that the type is a PR_FILE_FILE otherwise return a failure.
