From the stat() source code:
/* now set the common fields */
buf->st_uid = buf->st_gid = buf->st_ino = 0;
UID simply has no meaning on Windows. FYI, stat() as implemented in the
C Runtime Library is
broken on a large number of non-FAT, non-NTFS file systems. I strongly
recommend not using it.
What is needed is a mapping from UID to SID within the SMB logic; or
within an IFS.

Is it possible to determine AFS file ownership under Windows? It
appears that this can't be done because the _stat function call only
returns a 0 (zero) UID for a file in AFS space. Is this because
Microsoft hardcoded it to work this way, or because the AFS client
isn't providing the UID value to the _stat call?

<br>
I understand that Windows can't map the UID to a name because Windows
doesn't use a passwd file. So I was going to write a quick and dirty
app to translate the UID via PTS. I think tokens works this way? It
would be nicer for Windows users if there was a "fs listowner" or fs lo
command...a future?
