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:	ipa-4.5.4-10.el7_5.1	Doc Type:	Bug Fix
Doc Text:	Previously, a replication conflict could happen when running the ipa-replica-install utility in specific timing conditions. Due to the conflict, two service principals were created for the http/replica service. As a consequence, ipa-replica-install failed with the "KDC has no support for encryption type." error message. With this update, ipa-replica-install consistently communicates with a single master to create the service principal and the service keytab, which prevents potential replication conflicts. As a result, ipa-replica-install succeeds.	Story Points:	---

Comment 3 Mohammad Rizwan 2018-04-16 09:31:45 UTC

Version:
ipa-client-4.5.4-10.el7_5.1.x86_64
ipa-server-4.5.4-10.el7_5.1.x86_64
ipa-server-dns-4.5.4-10.el7_5.1.noarch

Steps:
1.  install ipa master with dns
2.  install ipa replica with dns
3.  point client to replica for dns
    $ echo "nameserver <replica-ip>" >> /etc/resolve.conf  (on client)

4.  stop ipa on master to make sure it's not used
5.  install ipa client
6.  run ipa cert-request

Actual result:

[root@client ~]# ipa cert-request --principal=HTTP/client.testrelm.test http-func-services.csr
