Description Dmitri Pal 2012-01-05 14:29:37 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/987

Currently, SSSD uses the following algorithm to determine which DNS domain to search for auto-discorvery:

 1. If {{{dns_discovery_domain}}} is set in sssd.conf, that is definitive.
 1. Try to use {{{hostname -d}}}
 1. Fall back to using the SSSD domain name in sssd.conf

It would be better if we used the search domains specified in {{{/etc/resolv.conf}}}

So I suggest the algorithm should be:

 1. If {{{dns_discovery_domain}}} is set in sssd.conf, that is definitive.
 1. Iterate through /etc/resolv.conf search domains
 1. Try to use {{{hostname -d}}}
 1. Fall back to using the SSSD domain name in sssd.conf

This way we'll prioritize the new approach, but leave the existing approach as a fallback option.

The upstream ticket is targetting 1.13, so I'm reproposing the BZ to RHEL-7.2

Thank you taking your time and submitting this request for Red Hat Enterprise Linux. Unfortunately, this bug was not given a priority and was deferred both in the upstream project and in Red Hat Enterprise Linux.

Given that we are unable to fulfill this request in following Red Hat Enterprise Linux releases, I am closing the Bugzilla as DEFERRED. To request that Red Hat re-considers the decision, please re-open the Bugzilla via appropriate support channels and provide additional business and/or technical details about its importance to you.

Note that you can still track this request or even contribute patches in the referred upstream Trac ticket.
