Ah, we just wrote almost the same in parallel :wink:

The documentation for SecLookupAccountSid is very confusing. If I were
writing that API, I would have allowed NULL for NameBuffer when NameSize
was 0. The description implies that NameSize is both input and output,
although the annotation says __out. Iā€™m also not clear on why NameSize
and DomainSize are present at all, since a UNICODE_STRING always
includes a maximum length field.

Exactly. I quickly looked to the implementation (Win7) and it is like this. Both sizes are output only and code checks for String->MaximumLength.
