Hello dochelp,

I can see inconsistency in what is published on
with regards to the changes introduced as a part of the Microsoft
Windows security update of November 2021. Could this inconsistency be
clarified by publishing the new revision of the MS-PAC document?

Errata document[1] talks about changes dated 2021/11/11 post V22.0 but the
rest of the linked documents are only V22.0.

In particular, the errata document[1] is saying:

The following sections were changed or added. Please see the diff document for the

In section 2.10 UPN_DNS_INFO, added four new fields and a flag to the
UPN_DNS_INFO structure.

In section 2.14 PAC_ATTRIBUTES_INFO, added section.

In section 2.15 PAC_REQUESTOR, added section.

The document published, however, does not have these changes. The last
section in chapter 2 is '14', there is no section 2.15.
