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: 389-ds-base-1.3.3.1-1.el7
Doc Type: Bug Fix
Doc Text:
Cause: The caller of an API slapi_valueset_add_attr_valuearray_ext was supposed to free the returned Slapi_ValueSet upon failure, but it was not done properly. Consequence: The Slapi_ValueSet was leaked when adding an attribute failed. Fix: The code to free the memory is added. Result: The returned Slapi_ValueSet does not get leaked.

Description Noriko Hosoi 2014-06-13 18:25:29 UTC 
+++ This bug was initially created as a clone of Bug #1109363 +++

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47455

This breaks slapi-nis.
https://git.fedorahosted.org/cgit/slapi-nis.git/tree/src/back-sch.c#n581

dn: cn=ng1,cn=ng,cn=compat,cn=accounts,dc=example,dc=com
objectClass: nisNetgroup
memberNisNetgroup: ng2
memberNisNetgroup: ng3
memberNisNetgroup: ng3

becomes

dn: cn=ng1,cn=ng,cn=compat,cn=accounts,dc=example,dc=com
objectClass: nisNetgroup
memberNisNetgroup: ng3

but it should be
dn: cn=ng1,cn=ng,cn=compat,cn=accounts,dc=example,dc=com
objectClass: nisNetgroup
memberNisNetgroup: ng2
memberNisNetgroup: ng3

That is, slapi_str2entry should just throw out the duplicate ng3 value and keep the ng2 value
