If I understand the documentation, I need to setup two idmap config,
one allocating ids for the BUILTIN users (using the tdb backend) and a
separate one for my domain users. I tought that using "*" would have
covered all domains, but I now think this is not true. Moreover, using
the rid backend, I found that not all users were listed until its range
was not large enough.

So, I changed the idmap config this way:

	idmap config * : range = 3000-7999
	idmap config * : backend = tdb
	idmap config AGENZIA : range = 8000-20000
	idmap config AGENZIA : backend = rid

I stopped the samba daemons, deleted the relevant tdb files, restarted
all daemons. I did not leave/join the domain again.

But I still have the same problem: "getent passwd" list all users,
while "getent passwd 'AGENZIA+manuelb'" does not give any results.

Thank you very much,
Giuseppe
