Apache Module mod_auth_basic

Description:Basic authentication
Module Identifier:auth_basic_module
Source File:mod_auth_basic.c
Compatibility:Available in Apache 2.1 and later


This module allows the use of HTTP Basic Authentication to restrict access by looking up users in the given providers. HTTP Digest Authentication is provided by mod_auth_digest. This module should usually be combined with at least one authentication module such as mod_authn_file and one authorization module such as mod_authz_user.


AuthBasicAuthoritative Directive

Description:Sets whether authorization and authentication are passed to lower level modules
Syntax:AuthBasicAuthoritative On|Off
Default:AuthBasicAuthoritative On
Context:directory, .htaccess

Normally, each authorization module listed in AuthBasicProvider will attempt to verify the user, and if the user is not found in any provider, access will be denied. Setting the AuthBasicAuthoritative directive explicitly to Off allows for both authentication and authorization to be passed on to other non-provider-based modules if there is no userID or rule matching the supplied userID. This should only be necessary when combining mod_auth_basic with third-party modules that are not configured with the AuthBasicProvider directive. When using such modules, the order of processing is determined in the modules' source code and is not configurable.


AuthBasicProvider Directive

Description:Sets the authentication provider(s) for this location
Syntax:AuthBasicProvider provider-name [provider-name] ...
Default:AuthBasicProvider file
Context:directory, .htaccess

The AuthBasicProvider directive sets which provider is used to authenticate the users for this location. The default file provider is implemented by the mod_authn_file module. Make sure that the chosen provider module is present in the server.


<Location /secure>
AuthType basic
AuthName "private area"
AuthBasicProvider dbm
AuthDBMUserFile /www/etc/dbmpasswd
Require valid-user

Providers are implemented by mod_authn_dbm, mod_authn_file, mod_authn_dbd, and mod_authnz_ldap.
