One can associate user names, not with the passwords, but with the 
digests of the passwords.  Then on user name and password verification, 
generate a digest or hash (such as MD5 or custom) of the password and 
check that against the file entry.  The password itself is never saved. 
  (Encrypting the file would not hurt, but now becomes less important.)

(I go to a special effort to minimize the chance that nothing other 
than the hash escapes from my passphrase controls.)
