Hello dochelp,

Looking at a fresh PAC from an updated win2019 DC, it appears two new
buffers were added, namely 17 and 18, as in this ticket.

ad-type: aD-WIN2K-PAC (128)
ad-data: 070000000000000001000000d801000078000000000000000a0000002400000050020000…
    Num Entries: 7
    Version: 0
    Type: Logon Info (1)
    Type: Client Info Type (10)
    Type: UPN DNS Info (12)
    Type: Unknown (17)
    Type: Unknown (18)

Can you please document these two new buffer types in the
corresponding table in MA-PAC 2.4 PAC_INFO_BUFFER table and their
corresponding logic.
