Sadly both this branch and v4-6-test fails autobuild in the Catalyst
cloud with the same error, so we cannot draw any conclusions as to the
effectiveness of this proposed solution:

[297(1142)/2043 at 32m16s] samba3.ntlm_auth.krb5 with old ccache(ktest:local)
UNEXPECTED(failure): samba3.ntlm_auth.krb5 with old ccache(ktest:local).ntlm_auth with krb5 gss-spnego-client and gss-spnego server(ktest:local)
REASON: Exception: Exception: could not obtain winbind domain name!
could not obtain winbind netbios name!
could not obtain winbind domain name!
could not obtain winbind separator!
Traceback (most recent call last):
  File "/home/ubuntu/autobuild/b29597/samba/source3/torture/test_ntlm_auth.py", line 329, in <module>
    main()
  File "/home/ubuntu/autobuild/b29597/samba/source3/torture/test_ntlm_auth.py", line 277, in main
    buf = readLine(client_in)
  File "/home/ubuntu/autobuild/b29597/samba/source3/torture/test_ntlm_auth.py", line 43, in readLine
    raise ReadChildError()
__main__.ReadChildError


In thinking about this, I don't see why attempting to provide an ldb
version that is backwards compatible to 4.6 is a task that has do be
done in the linear master repo, rather than in a branch unconstrained
by the release deadlines.  We should contain ourselves in the short
term to the patches that prevent building 4.6 with 1.2.0

The only good news is that I have confirmed that 4.6 fails with 1.1.31
for 'make test TESTS=fsmo', and that the proposed 1.1.32 fixes this
specific test. 

This took me the whole work day, so the lack of a clear resolution is a
little deflating, but I hope this helps.  

Please advise what the most useful next step towards a resolution here
is.

Thanks,

Andrew Bartlett
