   * ftpd.c (login): New function.  Essentially, the old pass
       function has been split into its two logical components, pass and
       login.
       (pass): If auth_ok is true, reply with code 202 to tell the
       user that a PASS command is not necessary.  Also, don't reply
       230 "User logged in" if the user didn't send a PASS command;
       this causes the client to get a bit confused.
       (auth_ok): New function that returns true if either gss_ok or
       kerb_ok is true (all the #ifdefs were beginning to clutter things,
       and it's a good abstraction in case other auth types are ever
       added in the future).
       (user): If GSSAPI or Kerberos v4 authentication succeeds, call
       login immediately, instead of waiting for the client to send "PASS
       dummy."  Also, use #ifdef PARANOID instead of "some paranoid sites
       may wish to uncomment this"
