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).

Comment 4 Rob Crittenden 2021-05-03 22:09:50 UTC 
It is failing while configuring the client parts on the server. Please attach /var/log/ipaclient-install.log as well.
Comment 5 Bijesh Thekkepat 2021-05-03 22:13:23 UTC 
Hello Rob,

Yes, the client part fails as well.
ipaclient-install-02930848.log is already attached, Comment 3

Let me know if you want it reattached.
Comment 6 Rob Crittenden 2021-05-04 15:51:34 UTC 
Sorry, I loaded the BZ before all attachments had been made.

It is failing trying to add a certificate to /etc/ipa/nssdb, the shared IPA system NSS database. The certutil command-line is logged after obfuscating any possible secrets and it is failing in that obfuscation step on the upper-case eñe (unicode /xd1) in the issuer subject.

Can you provide the output of:

ldapsearch -x -D 'cn=directory manager' -W -b cn=certificates,cn=ipa,cn=etc,dc=example,dc=test

replacing the dc's with the appropriate values for your domain?
Comment 12 Florence Blanc-Renaud 2021-06-09 12:10:29 UTC 
Issue can be reproduced on rhel 7.9 (with python2). The error happens when calling certutil to add the CA in the NSS databases. The parameter storing the nickname is a unicode and the method ipautil.run is expecting only string or bytes:
    arg_string = nolog_replace(' '.join(_log_arg(a) for a in args), nolog)

with the following definition for _log_arg:

if six.PY3:
    def _log_arg(s):
        """Convert string or bytes to a string suitable for logging"""
        if isinstance(s, bytes):
            return s.decode(locale.getpreferredencoding(),
                            errors='replace')
        else:
            return s
else:
    _log_arg = str

Since nickname is a utf-8 unicode, str(nickname) fails with encoding issue.
