mod_authn_default Authentication fallback module Base mod_authn_default.c authn_default_module Available in Apache 2.1 and later

This module is designed to be the fallback module, if you don't have configured an authentication module like mod_auth_basic. It simply rejects any credentials supplied by the user.

 AuthDefaultAuthoritative Sets whether authentication is passed to lower level modules AuthDefaultAuthoritative On|Off AuthDefaultAuthoritative On directory.htaccess AuthConfig

Setting the AuthDefaultAuthoritative directive explicitly to Off allows for authentication to be passed on to lower level modules (as defined in the modules.c files).

Note

Normally there are no lower level modules, since mod_authn_default is defined to be already on a very low level. Therefore you should leave the value of AuthDefaultAuthoritative as default (On).
