Authmemcookie is an apache2 authentication and authorization module. it does not make authentication by itself: the login page has to set an authentication cookie and store the user information in memcache. once a logged-in user tries to access a protected url, the module will verify if the authentication cookie is valid for the requested url and it will check the info stored in memcache in order to determine if the authenticated user is authorized to access the url. a sample ldap login page in php is included in the package.
