No. Do you want /etc/shadow world-WRITABLE, so users can change their
passwords? Or create a couple of files PER USER? Neither seems like a very
good idea.

More to the point, the SAM permissions do not correspond to file
permissions. OK, you could split user attributes up into three categories
(things they can change, things they can read, and things they cannot
access at all), and then have three files per user (YUK) - or just do it
the normal Unix way, and have the file accessable directly only by the
daemon, which then performs its own access control.
