Thanks for your suggestion. It looks like the SMB negotiation is OK:

   Starting GENSEC mechanism spnego
[2015/09/13 08:00:15.036667,  5] 
   Starting GENSEC submechanism ntlmssp
[2015/09/13 08:00:15.036829,  3] ../source3/smbd/negprot.c:385(reply_nt1)
   using SPNEGO
[2015/09/13 08:00:15.036867,  3] 
   Selected protocol NT LM 0.12
[2015/09/13 08:00:15.036897,  5] 
   negprot index=5

For good measure I added

max protocol = NT1

but no difference.
