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-3.0.0-1.el6
Doc Type: Bug Fix
Doc Text:
Cause: Administrators installing Identity Management were able to choose certificate subject base with a Common name (CN) as one component. However, it is illegal to have more than one CN attribute in a certificate subject. Consequence: Identity Management installation crashes. Fix: Do not allow CN attribute in a certificate subject base option. Result: Administrator is warned when he chooses a wrong certificate subject base.

Description Dmitri Pal 2012-04-10 16:12:10 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2584

The CN attribute is allowed in certificate subject base. However, when it is set, it makes installation fail:

{{{

Comment 1 RHEL Program Management 2012-07-10 07:13:06 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 2 RHEL Program Management 2012-07-10 23:27:01 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 3 Martin Kosek 2012-09-18 07:27:37 UTC 
Fixed upstream:

master: 390d708e43a71bf45b5a6e168277ebea483f473f - Installation fails when CN is set in certificate subject base

ipa-3-0: 390d708e43a71bf45b5a6e168277ebea483f473f - Installation fails when CN is set in certificate subject base

As having a multiple CNs values in a subject of a certificate is generally discouraged and can cause client issues (like the one reported), it is no longer allowed by ipa-server-install's --subject option.
Comment 5 Kaleem 2012-11-27 06:57:16 UTC 
Verified.

Now CN attribute is not allowed in subject parameter and error message is displayed.

IPA-Server version:
==================
[root@rhel64master install-server-cli]# rpm -q ipa-server
ipa-server-3.0.0-8.el6.x86_64
[root@rhel64master install-server-cli]#

[root@rhel64master ~]# ipa-server-install --setup-dns --forwarder=10.14.63.12 -r TESTRELM.COM -p xxxxxx -P xxxxxx -a xxxxxx -U --subject CN=Test
Usage: ipa-server-install [options]

ipa-server-install: error: --subject=CN=Test has invalid attribute: "CN"
