[Samba] Auth on OpenLDAP with idmap without Windows

[Scald Master]

Hi,

Let me know if this scenario is possible:
I want a samba server authenticating on OpenLDAP with IDMAP, without
creating any local user on server.

My environment is: many linux clients, a OpenLDAP server and some
services authenticating against it.
We don't use Active Directory nor we have any Windows server or client.

I don't know if this is possible and i've searched a lot through samba
documentation and on google.
All the documentation I found shows a samba always as a ADS Domain Member, like:
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/idmapper.html#id2607186

So my question is: It's possible to auth users on a samba server
against a OpenLDAP server without the need of a Windows environment?
To be honest, I don't need a Samba Domain, the server will be only a
file server.

I know is possible to auth NFS on LDAP but I don't like to use NFS,
and I think samba is way more reliable.

Thanks,
