Err. That would be a *really* bad idea. See the l0phtcrack
source for details :-).

Seriously, though. The password hashes used on NT are very
poor. They don't use salt and people are now speculating
on using the unicode regularity of NT hashes (alternating zero
bytes) to attack that further.

This is the reason I say in ENCRYPT.txt that the smbpasswd
file must be read only for root, no permissions to anyone
else. Oh, and it's also plaintext equivalent, as far as the
smb protocols are concerned. Making it available via NIS/YP
would be bad.
