Complete what I've seen (and then some)t of the PAC.
I haven't seen the rid+attr arrays for group membership, nor sids or the same kind of arrays for resource domains, so I don't know how that will work. Also, the PAC info type 10 is now decoded, but I don't know what it's for. It has an NTTIME, a 16-bit name length, and a username. According to M$, it's not needed, because they didn't doc it... (This used to be commit 28ab8504cf6c181866106e5cc626a5896283d0a9)
