This module provides the way for user authentication using the pwcheck
daemon from the Cyrus SASL package. This lets the authentication to be done
via the system password file without root permissions. The module also
optionally provides access control via the system group file instead of any
special group file used by the standard mod_auth_* modules.

Unless you wish to do access control using the system group file, then you
need any of the standard mod_auth_* modules to be in use.
