Hi Rowland,

I added "server max protocol = NT1" to my smb.conf file but no luck.

Request you tell me any other troubleshooting ideas for this setup.

Is it possible to join windows 2012 server with samba version 3.6.25 as
domain member?

Oh dear, it gets worse, not only are you running an EOL version of Samba, on
an EOL OS, you are also using smbldap-tools, which is, for all intents and
purposes, dead. 

I would urge you to upgrade everything, including upgrading your NT4-style
domain to an AD domain. 

In the meantime, you could try adding:

server max protocol = NT1

To your smb.conf
