 /* This implementation support Openwall-style TCB passwords in place of
  * traditional shadow, if the appropriate directories and files exist.
  * Thus, it is careful to avoid following symlinks or blocking on fifos
  * which a malicious user might create in place of his or her TCB shadow
  * file. It also avoids any allocation to prevent memory-exhaustion
  * attacks via huge TCB shadow files. */
