The following function works in Python (bear with me) :

from crypt import *
def encryptpasswd(passwd):
	salt = str(random.random())[2:4]
	cryptpasswd = crypt(passwd, salt)
	return cryptpasswd

This function takes a string 'passwd' and 
returns the encrypted password after a unix 'crypt'.
You don't need to understand Python to see that
I just use a 2 character string as the salt. 

The returned string 'cryptpasswd' is then put into the
master.passwd record; I then call pwd_mkdb and the 
passwd works. Screwy, i know, but it works - since this
is a one-way hash as opposed to encryption/decryption.

So, bottomline : try using a random 2 character string.
