mod_authz_default
Authorization fallback module
Base
mod_authz_default.c
authz_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 authorization module like mod_authz_user or mod_authz_groupfile. It simply rejects any authorization request.

AuthzDefaultAuthoritative
Sets whether authorization is passed to lower level modules
AuthzDefaultAuthoritative On|Off
AuthzDefaultAuthoritative On
directory
.htaccess
AuthConfig

Setting the AuthzDefaultAuthoritative directive explicitly to `Off` allows for authorization 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_authz_default is defined to be already on a very low level. Therefore you should leave the value of AuthzDefaultAuthoritative as default (`On`).
