// TODO: Currently, Each time we have to connct to the db twice, one to auth the
// user and the 2nd to get the info ??
// Groups with spaces'll screw us.
// ChangeLog:
// 2005-12-23: Use header(); instead of redirect();
// 2006-07-23: Ported to the new dokuwiki auth code.
// use mysql_real_escape_string()
// We now get the groups using a join instead of multiple queries.
// 2006-08-24: in getUserData(): Check that we have results when we try to get
// the user details from the database (Thanks Matthew Robinson of fone-me.com)
// 2006-08-30: Check that the user isn't blocked. Thanks alienbrain of EGLUG for the note.
// 2007-01-29: urldecode the username, password, hostname and path (Thanks Walter G).
// 2007-06-29: $db_url for drupal can be an array, we now account for this.
