does smbpasswd -r <host> need conf file?

[Michael Egan]

I seem to recall that Hobbit and Mudge (spelling?) discussed that the NT 
passwors do not use a salt. Another shortcomming.
If you set your password to be DOG on one domain, not only withh the 
first half of the encrypted version be the same on all the domains, but 
the last half will always start with CA CA (hex) since it is nulled, and 
the password tpyed is split and each split half is passed separately....
check out hsi paper on the passwords...
