    I suppose we are talking about this section of ssh 2.4.0's
    sshunixuser.c:
    
       940
       941	  /* Authentication is accepted if the encrypted passwords are
    identical. */
       942	#ifdef HAVE_HPUX_TCB_AUTH
       943	  return strncmp(encrypted_password, correct_passwd,
       944	                 strlen(correct_passwd)) == 0;
       945	#else /* HAVE_HPUX_TCB_AUTH */
       946	  return strcmp(encrypted_password, correct_passwd) == 0;
       947	#endif /* HAVE_HPUX_TCB_AUTH */
    
    If I read this correctly, it's certainly not a problem unless ssh is 
    compiled with HAVE_HPUX_TCB_AUTH defined.  In that case, it may or 
    may not be a problem.
