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 ident=
ical. */
   942	#ifdef HAVE_HPUX_TCB_AUTH
   943	  return strncmp(encrypted_password, correct_passwd,
   944	                 strlen(correct_passwd)) =3D=3D 0;
   945	#else /* HAVE_HPUX_TCB_AUTH */
   946	  return strcmp(encrypted_password, correct_passwd) =3D=3D 0;
   947	#endif /* HAVE_HPUX_TCB_AUTH */

If I read this correctly, it's certainly not a problem unless ssh is=20
compiled with HAVE_HPUX_TCB_AUTH defined.  In that case, it may or=20
may not be a problem.
