2066 <p>Distributed authentication enables a new user to input a username and password into the login box, and immediately be recognized, even if that user never registered at %site. This works because Drupal knows how to communicate with external registration databases. For example, lets say that new user 'Joe' is already a registered member of <a href=\"%delphi-forums\">Delphi Forums</a>. Drupal informs Joe on registration and login screens that he may login with his Delphi ID instead of registering with %site. Joe likes that idea, and logs in with a username of joe@remote.delphiforums.com and his usual Delphi password. Drupal then contacts the <em>remote.delphiforums.com</em> server behind the scenes (usually using <a href=\"%xml\">XML-RPC</a>, <a href=\"%http-post\">HTTP POST</a>, or <a href=\"%soap\">SOAP</a>) and asks: \"Is the password for user Joe correct?\". If Delphi replies yes, then we create a new %site account for Joe and log him into it. Joe may keep on logging into %site in the same manner, and he will always be logged into the same account.</p>", array('%help-links' => (implode(', ', user_auth_help_links())), '%site' => "<em>$site</em>", '%drupal' => 'http://drupal.org', '%delphi-forums' => 'http://www.delphiforums.com', '%xml' => 'http://www.xmlrpc.com', '%http-post' => 'http://www.w3.org/Protocols/', '%soap' => 'http://www.soapware.org'));
