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 2014-01-21 14:30:01 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/4126

ipasam needs to change to delete first all child domains and then remove the trusted domain because LDAP API does not support deleting non-leaf entries.
Comment 1 Martin Kosek 2014-01-21 16:23:42 UTC

Comment 2 Namita Soman 2014-01-21 16:31:12 UTC 
Please add steps to verify
Comment 3 Alexander Bokovoy 2014-01-21 19:25:05 UTC 
Steps to verify:
1. Install IPA from scratch

2. Enable AD trusts with ipa-adtrust-install

3. Establish trust to an AD forest with at least root forest domain and a domain child:
   kinit admin
   ipa trust-add ...

4. Enable debugging in Samba: 
   smbcontrol smbd debug 10

5. Re-establish trust with 'ipa trust-add ...'

6. Disable debugging in Samba:
   smbcontrol smbd debug 1

7. Check that Samba logs do contain an error on attempting to delete non-leaf LDAP entry and then almost immediately successful deletes of first a child domain and then the forest trust root domain:

No '(smbldap_delete:|Failed to delete)' logs found. Is this the expected result?

Comment 6 Alexander Bokovoy 2014-02-11 08:47:56 UTC 
I've looked into two different test machines Steve prepared for verifying this bug and found out that the code works correctly. However, communication with AD DC is broken due to incorrectly configured firewalld.

As soon as firewalld was stopped (and iptables configuration was cleared), everything started working properly.

While we need to improve firewalld configuration for IPA cases, I think with clean firewall we can verify this bug.
