samba - Jul 2010 - Anyone had success: Samba4, idmap_ldap (alloc only), idmap_adex

After spending some time trying to figure out how to merge the 
allocating backend from idmap_ldap and the rest of idmap_adex, I have 
found that it may not be worth the effort to avoid having to configure 
idmap_ldap.

Has anyone had success with idmap_ldap as the uid/gid allocator and 
idmap_adex in Samba4? I haven't done much with ldap, so any instructions 
on how to add schema info needed for idmap_ldap (if any) to Samba4 and 
an example configuration would be greatly appreciated.

Thank you,
