...and there's no ASCII password?

Unicode Plaintext is a very unusual combination.  I have tested this 
combination before (Samba can be made to do it) but since we've never had 
anything to test against...

Tcpdump is perfect.  :)

Oh!  ...but use a bogus password, or change the password after you've 
captured the data.  I don't want your "real" auth data.  :)

Send directly to me, please.  If anyone else on the Team wants a look I'll
share.  I may run it past a few other folks as well, and I would love to
have the information for my book.

Thanks!
