Description Marko Myllynen 2011-10-25 13:46:36 UTC

Description of problem:
When using "net ads join" to join to an AD domain it usually works nicely and SPN for HTTP and the related key in the keytab can be successfully generated, users can then access Kerberos authenticated pages served by the host with AD tickets.

However, sometimes "net ads join" seems to partially fail to join to domain properly, a kerberos error is printed during join although the machine account has been created on AD. Then creating the SPN/HTTP doesn't work unless leaving the domain and rejoining.

I'll attach full debug logs from a customer environment after a fully successful and problematic join attempts followed by "net ads status" output.

Version-Release number of selected component (if applicable):
samba-3.5.10-99.el6

Comment 6 Marko Myllynen 2011-10-26 11:50:04 UTC

This actually comes up only when one of the DCs in the domain is unreachable, if specifying a known-good server (net ads join -S ...) then join/leave always work reliably.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 33 RHEL Program Management 2012-07-11 01:53:27 UTC

This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Comment 34 Andreas Schneider 2012-08-03 09:09:53 UTC

We can't reproduce it, but we are certain that it has been fixed in 3.6.6. See comment #30.

Comment 36 Marko Myllynen 2012-08-07 11:54:43 UTC

I've now tested samba-3.6.6-126.el6 and haven't seen any failures to join a domain so far so it certainly seems that this was caused by https://bugzilla.samba.org/show_bug.cgi?id=8897.

Thanks!
