no, I knew about that one.

Note that the request has a SID in it, but the response doesn't. The
only way we could need the SID is if we need to respond differently
for different SID or username values. Can you think of a situation
where that is needed?

I think this could only happen if a Samba server were only serving
a subset of the users in a domain. We don't support that (AFAIK).
