Merge from branches/authz-dev Basically here is a list of what has been done: - Convert all of the authz modules from hook based to provider based - Remove the ap_requires field from the core_dir_config structure - Remove the function ap_requires() since its functionality is no longer supported or necessary in the refactoring - Remove the calls to ap_some_auth_required() in the core request handling to allow the hooks to be called in all cases. - Add the new module mod_authz_core which will act as the authorization provider vector and contain common authz directives such as 'Require', 'Reject' and '<RequireAlias>' - Add the new module mod_authn_core which will contain common authentication directives such as 'AuthType', 'AuthName' and '<AuthnProviderAlias>' - Move the check for METHOD_MASK out of the authz providers and into the authz_core provider vector - Define the status codes that can be returned by the authz providers as AUTHZ_DENIED, AUTHZ_GRANTED and AUTHZ_GENERAL_ERROR - Remove the 'Satisfy' directive - Implement the '<RequireAll>', '<RequireOne>' block directives to handle the 'and' and 'or' logic for authorization. - Remove the 'AuthzXXXAuthoritative' directives from all of the authz providers - Implement the 'Reject' directive that will deny authorization if the argument is true - Fold the 'Reject' directive into the '<RequireAll>', '<RequireOne>' logic - Reimplement the host based authorization functionality provided by 'allow', 'deny' and 'order' as authz providers - Remove the 'allow', 'deny' and 'order' directives - Merge mod_authn_alias into mod_authn_core - Add '<RequireAlias>' functionality which is similar to '<AuthnProviderAlias>' but specific to authorization aliasing - Remove all of the references to the 'authzxxxAuthoritative' directives from the documentation - Remove the 'Satisfy' directive from the documentation - Remove 'Allow', 'Deny', 'Order' directives from the documentation - Document '<RequireAll>', '<RequireOne>', 'Reject' directives - Reimplement the APIs ap_auth_type(), ap_auth_name() as optional functions and move the actual implementation into mod_authn_core - Reimplement the API ap_some_auth_required() as an optional function and move the actual implementation into mod_authz_core Major Changes: - Added the directives <RequireAll>, <RequireOne>, <RequireAlias>, Reject - Expanded the functionality of the directive 'Require' to handle all authorization and access control - Added the new authz providers 'env', 'ip', 'host', 'all' to handle host-based access control - Removed the directives 'Allow', 'Deny', 'Order', 'Satisfy', 'AuthzXXXAuthoritative' - Removed the ap_require() API - Moved the directives 'AuthType', 'AuthName' out of mod_core and into mod_authn_core - Moved the directive 'Require' out of mod_core and into mod_authz_core - Merged mod_authn_alias into mod_authn_core - Renamed mod_authz_dbm authz providers from 'group' and 'file-group' to 'dbm-group' and 'dbm-file-group' Benefits: - All authorization and access control is now handle through two directives, 'Require' and 'Reject' - Authorization has been expanded to allow for complex 'AND/OR' control logic through the directives '<RequireAll>' and '<RequireOne>' - Configuration is now much simpler and consistent across the board - Other modules like mod_ssl and mod_proxy should be able to plug into and take advantage of the same provider based authorization mechanism by implementing their own providers Issues: - Backwards compatibility between 2.2 and 2.3 configurations will be broken in the area of authorization and access control due to the fact that the directives 'allow', 'deny', 'order' and 'satisfy' have been removed. When moving from 2.2 to 2.3 these directives will have to be changed to 'Require all granted', 'Require all denied' or some variation of the authz host-based providers. - Existing third party authorization modules will have to adapt to the new structure. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@368027 13f79535-47bb-0310-9956-ffa450edef68

<p>This module provides authorization capabilities so that

authenticated users can be allowed or denied access to portions
|
|
of the web site. <module>mod_authz_user</module> grants
|
|
access if the authenticated user is listed in a <code>Require user</code>
|

directive. Alternatively <code>require valid-user</code> can be used to
|
|
grant access to all successfully authenticated users.</p>
