on registration and login screens that he may login with his Delphi ID instead

of registering with %s. Joe likes that idea, and logs in with a username

of joe@remote.delphiforums.com and his usual Delphi password. Drupal then contacts

we create a new $site account for Joe and log him into it. Joe may keep

This works because Drupal knows how to communicate with external registration databases. For example, lets say that your new user 'Joe' is already a registered member of Delphi Forums. If your Drupal has delphi.module installed, then Drupal will inform Joe on the registration and login screens that he may login with his Delphi ID instead of registering with your Drupal instance. Joe likes that idea, and logs in with a username of joe@remote.delphiforums.com and his usual Delphi password. Drupal then communicates with remote.delphiforums.com (usually using ". l("XML-RPC","www.xmlrpc.com") ." ". l("HTTP POST", "www.w3.org/Protocols/") .", or ". l("SOAP", "www.soapware.org") .") behind the scenes and asks "is this password for username=joe?" If Delphi replies yes, then Drupal will create a new local account for joe and log joe into it. Joe may keep on logging into your Drupal instance in the same manner, and he will be logged into the same joe@remote.delphiforums.com account.</p>";

$output .= "<p>One key element of DA is the 'authmap' table, which maps a user's authname (e.g. joe@remote.delphiforums.com) to his local UID (i.e. universal identification number). This map is checked whenever a user successfully logs into an external authentication source. Once Drupal knows that the current user is definately joe@remote.delphiforums.com (because Delphi says so), he looks up Joe's UID and logs Joe into that account.</p>";

One peculiarity of this module is that we don't actually use the $server parameter. Blogger only accepts authentication at <i>plant.blogger.com</i>, so we hard-code that value into the <i>xmlrpc_client()</i> function. A more typical example might be the jabber module, which uses the <i>\$server</i> parameter to determine where to send the authentication request. Also of note is the '5' parameter in the <i>\$client->send\(\)</i> call. This is a timeout value in seconds. All authentication modules should implement a timeout on their external calls.
