See description. This is a regression since FreeIPA 4.4.0.




Hi Alexander,

Please link upstream ticket[1] to the commit message, not BZ.

I have put on my Travis hat and found:

1.) pep8 error:

./ipaserver/plugins/trust.py:1623:25: E128 continuation line under-indented for visual indent

I know that this is a piece of code that was only moved around but it should conform to pep8 anyway.

2.) unused variable:

Pylint is running, please wait ...
************* Module ipaserver.plugins.trust
ipaserver/plugins/trust.py:1619: [W0612(unused-variable), trustdomain_del.execute] Unused variable 'entry')
Makefile:130: recipe for target 'pylint' failed
make: *** [pylint] Error 1

Also, if you just want to check if the domain exists, I think that you can use `get_dn_if_exists` method of LDAPObject (you will get rid of unused variable as a bonus):

Thanks, I've fixed these issues.

Updated patch is attached.

Subject: [PATCH 2/2] trustdomain-del: fix the way how subdomain is searched

With FreeIPA 4.4 we moved child domains behind the 'trustdomain' topic.
Update 'ipa trustdomain-del' command to properly calculate DN to the
actual child domain and handle the case when it is missing correctly.

Fixes https://fedorahosted.org/freeipa/ticket/6445
