1) Does 'getent passwd policia\gafranchello' produce output when run on a
Unix client ?
If try to logon on unis console

2) What are the 'other purposes' you are using LDAP for ? Most, if not all,
can be added to Samba AD.

The think is very complex because we have various products authenticating
whith ldap squid/git/syspass/moodle/openfire/zentyal/etc  and we are
modified and adapted the ldap schema with some ldap entries for this
products, the samba schema in the same schema (we have only one lsap
schema), and we interactive with this via a ad hoc developed interface.
Change or update samba to samba 4 AD implies that we have change the unis
schema, receding the interface, proves, etc it is to much time.

We try once to implemente samba 4 AD and notice that the ldap schema are
very different that we have, so many changes, that implies to many
development on the interface.

Know I thinking that is posible to make another ldap schema just for samba
4 AD and continue using the other for rest of products, but this implies to
redising the interface to update users, groups on both schemas.

Another question: Thinking on samba 4 AD, when a user logon on desktop
client, it can map o access direct to resources shared on samba server or
need to authenticate almost at once ? Because actually on windows clients
this is not needed, when a user logon on domain can map or access shared
folders whitout authentication again.
