Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Petr Vobornik 2016-07-15 11:53:20 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/6028

When renaming a user who already has some principal aliases associated with the entry, the MODRDN plugin is triggered and it sets the value of krbPrincipalName to the alias composed from the new UID. However, this operation destroys all other values of the attribute:

{{{
ipa user-add-principal tuser talias\\@tupn.test
---------------------------------
Added new aliases to user "tuser"
---------------------------------
  User login: tuser
  Principal alias: talias\@tupn.test, tuser

[root@master1 ~]# ipa user-mod --rename tuser2 tuser
---------------------
Modified user "tuser"
---------------------
  User login: tuser2
  First name: test
  Last name: user
  Home directory: /home/tuser
  Login shell: /bin/sh
  Principal name: tuser2
  Principal alias: tuser2
  Email address: tuser
  UID: 602400001
  GID: 602400001
  Account disabled: False
  Password: True
  Member of groups: ipausers
  Kerberos keys available: True

}}}

Expected outcome:

The user gains new alias contaning new uid

Actual results:

Only this alias is retained and all other are removed
