In Samba 3.* ldapsam is a built-in sam backend, you don't have to pass 
any arguments to configure for it.
If you configure --with-ldapsam, then you enable the so called 
ldapsam-compat sam backend, which is the ldap backend (with the same 
schema) of samba 2.2.* .
If you want to use the new (3.* specific)  ldapsam, then you need to specify
passdb = ldapsam:ldap[s]://yourserver:yourserverport,
and no ldap server = yourserver
