[Samba] Authenticate Samba with an LDAP w/o the schema

[Fabrizio Reale]

Hi all,
I'd like to authenticate my fresh Samba installation against an LDAP server 
without the Samba schema. Obviously I cannot touch it.

So I'd like to use LDAP just for the authentication without getting
the UID and the other parameters from it.
I can use the same UID, home folder and so on for all the users, the only 
important thing is to provide access only to the LDAP users.

Is it possible?

Thank you,
Fabrizio
