[Samba] Samba and trusted domains

[Michael Gasch]

for trusted domains to work you have to use either tdbsam or ldap 
backend. don´t know whether ad works, though.

this should work for you:
#	idmap backend =		# please comment out for tdbsam
	idmap uid = 10000-100000
	idmap gid = 10000-100000
         winbind use default domain = Yes	# your choice
         winbind trusted domains only = no	# must
         allow trusted domains = yes		# must
