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.

### Issue
changing the freeipa ui apache server cert fails.

ipa-server-certinstall -w -p whatever  --pin=""   /etc/ssl/a.pem.crt   /etc/ssl/private/a.pem.key
fails with

#### Steps to Reproduce
See above, 100%

Change
def add_subject(request_id, subject):
    """
    In order for a certmonger request to be renwable it needs the subject
    set in the request file.

    When an existing certificate is added via start-tracking it won't have
    a subject_template set. !!!
    """
-    add_request_value(request_id, 'template-subject', subject)
+    add_request_value(request_id, 'template-subject', str(subject))

and it works.
certmonger/eoan,now 0.79.6-2 amd64 [installed,automatic]

I'm concerned my 'fix' will not result in certmonger actually doing the right thing, but at least the command completes 'normally'.  I'll leave it to the freeipa brain trust from here.
Comment 2 Rob Crittenden 2020-04-01 12:30:02 UTC 
This is seen when replacing a certificate with one issued by IPA.

The call to fix is in ipaserver/install/ipa_server_certinstall.py before the add_subject call.

The typical usage is: subject = str(DN(cert.subject))

Rob,
Thanks.
This patch corrects the error above.

Comment 11 Sergey Orlov 2021-07-02 14:43:47 UTC 
Verified using latest nightly compose with ipa-server-4.9.5-1.module+el8.5.0+11410+91a33fe4.x86_64

Upstream test suite  test_installation.py is broken in RHEL8.5, thus verifyed by manually executing steps from test_installation.py::TestInstallCA::test_cert_install_with_IPA_issued_cert:

# ipa-server-install -a Secret123 -p Secret123  -n testrelm.test -U -r TESTRELM.TEST
...
The ipa-server-install command was successful


# cp -p /var/lib/ipa/certs/httpd.crt /tmp/
# cp -p /var/lib/ipa/private/httpd.key /tmp/

# export PASSWD="/var/lib/ipa/passwds/`hostname`-443-RSA"
# export PASSWD_STR=`cat $PASSWD`

# ipa-server-certinstall -p Secret123 -w --pin "$PASSWD" /tmp/httpd.crt /tmp/httpd.key
Please restart ipa services after installing certificate (ipactl restart)
The ipa-server-certinstall command was successful
