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:

{{{
$ ipa-server-install ... --subject CN=Test

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"
