| Description: | Authentication fallback module | 
|---|---|
| Status: | Base | 
| Module Identifier: | authn_default_module | 
| Source File: | mod_authn_default.c | 
| Compatibility: | 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.
| Description: | Sets whether authentication is passed to lower level modules | 
|---|---|
| Syntax: | AuthDefaultAuthoritative On|Off | 
| Default: | AuthDefaultAuthoritative On | 
| Context: | directory, .htaccess | 
| Override: | AuthConfig | 
| Status: | Base | 
| Module: | mod_authn_default | 
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).
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).
