mod_authz_user User Authorization Base mod_authz_user.c authz_user_module Available in Apache 2.1 and later

This module provides authorization capabilities so that authenticated users can be allowed or denied access to portions of the web site. mod_authz_user grants access if the authenticated user is listed in a Require user directive. Alternatively Require valid-user can be used to grant access to all successfully authenticated users.

Require Satisfy AuthzUserAuthoritative Sets whether authorization will be passed on to lower level modules AuthzUserAuthoritative On|Off AuthzUserAuthoritative On directory.htaccess AuthConfig

Setting the AuthzUserAuthoritative directive explicitly to Off allows for user authorization to be passed on to lower level modules (as defined in the modules.c files) if there is no user matching the supplied userID.

By default, control is not passed on and an unknown user will result in an Authentication Required reply. Not setting it to Off thus keeps the system secure and forces an NCSA compliant behaviour.
