- lib/unix_sec_ctxt.c
attempt at taking lib/uid.c and getting a unix security context
change module that is independent of "cnums" and "snums".
a security context is needed for pipes, not just IPC$ or other
services.
- group database API
added add_group/alias_member, del_group/alias_member,
del_group/alias_entry functions. del_builtin_entry() is
deliberately set to NULL to cause an exception, you cannot
delete builtin aliases.
- parse_lsa.c srv_lsa.c
fixed lookup_names code, it was a load of trash and didn't do
anything.
- cmd_samr.c rpcclient.c srv_samr.c
added "deletegroup", "deletealias", "delaliasmem", "delgroupmem",
"addgroupmem", "addaliasmem", "createalias", "creategroup", to
both client and server code.
server code calls into unix stubs right now, which don't actually
do anything. the only instance where they are expected to do
anything is in appliance mode NOT even in the ldap code or anything.
client code modified to call samr_lookup_names() for group code
(because we can) and lsa_lookup_names() for alias code (because
we have to).
- srv_lookup.c
oops, lookup on unsplit name, we got lookup on DOMAIN, DOMAIN\name
instead of DOMAIN, name.
