a new tdb is not required. The new group mapping code in HEAD has all the
infrastructure to store privileges now. I need to work on the tdbsam user
backend to add privileges to users too.

the remaining are subset of this ones, or more exactly GENERIC_xxx are
made from others bitmasks.

You should find all the informations in the MSDN, do a search on "LSA" or
"LsaOpenPolicy", should give you a starting point.

oh no not at all a degree of complexity.

all I have to do is add something like:

	if(!se_check_privilege(p->current_user->token,  MINIMUM_NECESSARY_PRIVILEGE))

at the beginning of each functions in srv_lsa_nt.c and srv_samr_nt.c
