3.21  Apache Module mod_authz_user



Description:

User Authorization

Status:

Base

Module Identifier:

authz_user_module

Source File:

mod_authz_user.c

Compatibility:

Available in Apache 2.1 and later



Summary

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.

Directives:

AuthzUserAuthoritative

See also:

AuthzUserAuthoritative Directive

Description:

Sets whether authorization will be passed on to lower level modules

Syntax:

AuthzUserAuthoritative On|Off

Default:

AuthzUserAuthoritative On

Context:

directory, .htaccess

Override:

AuthConfig

Status:

Base

Module:

mod_authz_user

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.
