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 German Parente 2018-11-06 14:12:50 UTC
Description of problem:

This is the RHEL7 bug corresponding to upstream:

#49859 A distinguished value of a single valued attribute can be missing in an entry


In MMR with a specific set of operations it is possible to create an entry like

dn: employeeNumber=3.2,ou=distinguished,ou=People,dc=example,dc=com
employeeNumber: 3.1
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
uid: 3
sn: 3
cn: 3

The test case is composed of 3 Masters but it is equivalent with 2 Masters.
Topology is fully meshed but RA from M1 and M2 are disabled.

1 - On M1 MODRDN (E, rdn=employeeNumber=3.1)
2 - On M2 MODRDN (E, rdn=employeeNumber=3.2)
3 - On M1 MOD(E, [MOD_REPL, 'employeeNumber', '3.1'])

The entry is similar on all servers. The csn of (3) being the higher than (2), the MOD will remove the value '3.2' without taking into consideration that it is distinguished

Version-Release number of selected component (if applicable): RHEL7.6



Steps to Reproduce: follow test case in DS #49859 
1.
2.
3.

Actual results:

the value of the the RDN attribute is not present in the entry
