/**
 * DBService
 *
 * This class is a wrapper for the dbService servlet.  The dbService
 * servlet acts as a frontend to the database that stores info on users,
 * portal parameters, and IdPs. This was created to allow for fast
 * access to the database by keeping a connection open.  This class is a
 * rework of the old store.php class.
 *
 * Example usage:
 *     // For authentication, we have a bunch of attributes from an
 *     // identity provider. Thus get the database uid for the user
 *     // by using the multi-parameter version of getUser().
 *     $uid = '';
 *     $dbservice = new DBService();
 *     $dbservice->getUser('[email protected]',
 *                         'urn:mace:incommon:uiuc.edu',
 *                         'University of Illinois at Urbana-Champaign',
 *                         'John','Smith','John Smith,
 *                          '[email protected]');
 *     if (!($dbservice->status & 1)) { // OK status codes are even
 *         $uid = $dbservice->user_uid;
 *     }
 *
 *     // Later in the code, re-fetch the user using this uid
 *     // and print out the stored attributes.
 *     if (strlen($uid) > 0) {
 *         $dbservice->getUser($uid);
 *         echo 'Name = ' . $dbservice->first_name . ' ' .
 *                          $dbservice->last_name  . "\n";
 *         echo 'DN = '   . $dbservice->distinguished_name . "\n";
 *     }
 *
 *     // For getting/setting the Shibboleth-based IdPs, use the
 *     // getIdps()/setIdps() methods.  These methods utilize the
 *     // class member array $idp_uids for reading/writing. Two
 *     // convenience methods (setIdpsFromKeys($array) and
 *     // setIdpsFromValues($array)) are provided to populate the
 *     // $idp_uids array from the passed-in $array.
 *     $dbservice->getIdps();
 *     foreach($dbservice->idp_uids as $value) {
 *         echo "$value\n";
 *     }
 *
 *     $idps = array('urn:mace:incommon:ucsd.edu',
 *                   'urn:mace:incommon:uiuc.edu');
 *     $dbservice->setIdpsFromValues($idps);
 *     //   --- OR ---
 *     $idps = array('urn:mace:incommon:ucsd.edu' => 1,
 *                   'urn:mace:incommon:uiuc.edu' => 1);
