Description Petr Vobornik 2017-04-04 06:05:04 EDT 
Cloned from upstream: https://pagure.io/freeipa/issue/6831

In order to fully support PKINIT configuration in CA-less deployments, the tools that manipulate 3rd party certificates must be extended to also install PKINIT server certificates and update KDC's PKINIT anchors when 3rd party CA certificates are to be used.

Comment 9 Michal Reznik 2017-06-09 09:04:52 EDT 
Moving to assigned as verification failed:

ipa-server-4.5.0-16.el7.x86_64
selinux-policy-3.13.1-160.el7.noarch

Followed these steps:

1. install CA-less master without pkinit
2. generate KDC cert signed by different CA
3. issue "ipa-cacert-manage install" to add the CA
4. ipa-certupdate
5. ipa-server-certinstall --kdc ./pkinit-server.p12 --pin XXX
6. kinit -n

When attempting to get the anonymous ticket got:

After restarting krb5kdc service it works:

[root@master ~]# systemctl restart krb5kdc.service
[root@master ~]# 
[root@master ~]# kinit -n
[root@master ~]# 
[root@master ~]# klist

[root@master ~]# 
[root@master ~]# getenforce

[root@master ~]# ausearch -m avc

However manual restart should not be required obviously.

The issue looks like https://pagure.io/freeipa/issue/7003 however this time are not after an upgrade.

Update to comment #9. It turned out that there is currently no restart in "ipa_server_certinstall.py" code. In this case the restart is really expected.
