Description Giuseppe Ragusa 2012-08-06 13:20:01 EDT
Description of problem:
Now that Bind has been rebased to 9.8.x it is possible to provide support for the Samba4-provided external DLZ module for AD-backed zones (currently the only DNS solution capable of secure DDNS in Samba4); unfortunately, this support is not enabled in current builds of Bind in RHEL6.

Version-Release number of selected component (if applicable):

How reproducible:
Try to configure the Bind DLZ module in Samba4.

Steps to Reproduce:
Actual results:
External DLZ modules not supported.

Expected results:
Samba4-provided external DLZ module is correctly loaded.

Additional info:
Simply adding the "--with-dlopen=yes" option to the %configure part of the spec enabled such support; no adverse effects are expected for the other already shipped parts of Bind.
Note that bind-chroot support for the Samba4-provided module could require additional careful configuration.
Comment 2 Giuseppe Ragusa 2012-09-04 06:16:08 EDT
After additional testing I suspect that the failures where probably due to other problems on the Samba4 side of things.

Furthermore Bind docs suggest that "--with-dlopen=yes" should be the default in versions >= 9.8.1

I'm going to test with the standard Bind package again asap and will report back.
Comment 5 RHEL Product and Program Management 2013-10-13 20:32:01 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
