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.

Description Alexander Bokovoy 2019-08-16 11:29:17 UTC 
+++ This bug was initially created as a clone of Bug #1705072 +++

FreeIPA by default configures location-specific templates for _ldap._tcp, _kerberos._tcp, _kerberos._udp, and _kpasswd._tcp CNAME records. However, a default deployment has no location defined. This means a template expansion inside bind-dyndb-ldap fails with an error message:

30-Apr-2019 16:54:06.882 dns_rdatatype_fromtext() failed for attribute 'idnsTemplateAttribute;cnamerecord': unknown class/type

The code then proceeds to create a staticly defined content of the CNAME record. However, a bug in that code actually creates two records: one with unexpanded CNAME value:

30-Apr-2019 16:54:06.882 setting 'substitutionvariable_ipalocation' is not defined so it cannot be substituted into template '_ldap._tcp.\{substitutionvariable_ipalocation\}._locations'

and another one with the actual A/AAAA entry for the server.

As result, DNS resolution of the CNAME record fails from external clients and new machines cannot be enrolled into IPA.
