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
