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 Mike 2010-12-06 14:37:25 UTC 
Description of problem:
We have an AD domain that spans two datacenters, and we use custom SRV records so that clients connect to site-local AD servers, and only connect to servers in the other site if all local servers are unavailable.  

We are able to specific a custom SRV record in nss_ldap using the nss_srv_domain option, but if sssd is the preferred method in RHEL6, we need a similiar option.

The "dns_discovery_domain" option has been added in upstream, and we'd like it available in RHEL6.

Version-Release number of selected component (if applicable):
sssd-1.2.1-28.el6.x86_64
Comment 4 Kaushik Banerjee 2011-04-07 12:02:50 UTC 
"dns_discovery_domain" feature works now.

On using "dns_discovery_domain = sssdad.com", sssd uses the domain name appropriately and resolves the SRV record.
