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 Dmitri Pal 2012-11-20 14:36:06 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/3261

`ipa trust-add` command recommends DNS forwarder set-up but it should recommend normal DNS delegation in first place. Forwarders should be option of last resort.


Current output:
{{{
[root@cypher ~]# ipa trust-add --type=ad adlab.qe --admin Administrator --password
Active directory domain administrator's password:
ipa: ERROR: Unable to resolve domain controller for 'adlab.qe' domain.
Additional instructions:
IPA manages DNS, please configure forwarder to 'adlab.qe' domain using following CLI command. Make sure to replace DNS_SERVER and IP_ADDRESS by actual values corresponding to the trusted domain's DNS server:
    ipa dnszone-add adlab.qe --name-server=[DNS_SERVER] --admin-email='hostmaster' --force --forwarder=[IP_ADDRESS] --forward-policy=only
When using Web UI, please create DNS zone for domain 'adlab.qe' first and then set forwarder and forward policy. 
}}}

It should say somenthing like:
{{{
IPA manages DNS, please create delegation records (NS + A or AAAA records) for AD managed DNS domains.

NS record for name 'adlab' in zone 'qe' should countain *name* of AD name server. A or AAAA glue records for AD name server have to be created to ensure proper name server resolution.

If you set global forwarders (in named.conf or in LDAP) to value different from your AD server then you should specify forward policy to 'none' for zone 'qe.'. Implicit policy 'first' will send all queries to global forwarders and NS records will be ineffective.

You can set DNS forwarding up if you can't create delegation records for some reason.
... original text follows ...
}}}

Conversation to clarify difference in description and result
<steeve> sbose: https://bugzilla.redhat.com/show_bug.cgi?id=878485
<steeve> sbose: Is this expected http://pastebin.test.redhat.com/125629 for the above bug?
<sbose> steeve, I think so, anything wrong with it?
* enewland has quit (Quit: Leaving)
* enewland (~enewland.redhat.com) has joined #ipa
<ab> steeve: there was discussion on ipa team list to remove configuration description in favor of documentation
<steeve> sbose: no. It was different from the description
<ab> steeve: since there are quite few variations
<ab> so I would say what you see in pastebin is correct and what is expected.
<steeve> sbose: ab  ok.. Thanks!
* arubin (~arubin.redhat.com) has joined #ipa
<sbose> steeve, ah, ok, we agreed to not give any specific suggestion because other solution might be better in specific environments.
<steeve> sbose: yes.. makes sense
