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 Rich Megginson 2012-05-17 20:08:44 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/361

Version 1.2.10 segfaults on start up if an ACI has an bad DN. The segmentation fault occurs during the parsing of the ACI in function __aclp__copy_normalized_str. I tracked the defect to this commit:

http://git.fedorahosted.org/git/?p=389/ds.git;a=commitdiff;h=f6397113666f06848412bb12f754f04258cfa5fa

A bad DN can will make the DN normalization fail which is not tested any more. I am attaching a trivial patch that tests for this case and returns -1 when the normalization failed, thus restoring the previous behaviour of the function.

Executed test "ticket361" in acl/syntax.sh
AND

quickinstall startup 	100% (2/2) 	  	 
Acl startup(o=ace industry,c=us) 	100% (1/1) 	  	 
Acl run(o=ace industry,c=us) 	100% (1/1) 	  	 
Acl cleanup 	100% (1/1) 	 

So marking the test as PASSED.
