Yes, I understand - but that is not what the problem is at my end.

As it stands, the Solaris bundled Samba version (3.5.8) joins the
2008R2 AD just fine (same settings, same everything), whereas the
compiled version (3.6.9) doesn't: it comes back with

Failed to join domain: failed to lookup DC info for domain
'EXCH2010.MS.TEST.XX.XXX.AU' over rpc: Logon failure

See the attached log from the failure.

The only mention of a similar problem is this thread back in 2011:

It is not clear to me how the OP fixed it.
