I do not use zentyal, so I am not sure about upgrading it. Zentyal isn't 
a Samba product, it is a Distro that uses Samba. I seem to remember that 
3.2 used openldap as well as Samba, I am unsure just how Samba was used.

What I am trying to point out is, you will probably get better help 
asking on the zentyal forum. If it can be confirmed that zentyal 3.2 
does use Samba as an AD DC (and not an NT4-style DC) then you might be 
able to join an earlier version of Samba to it and then go from there.

As to finding out what ldap is being used for, you could try using 
ldapsearch to dump to a file and then examine this.
