Auth_HTTP Problem

Hi all, I am trying out the example code in the pear docs for Auth_HTTP, but I can't get the code to run. Actually, including the class at all causes everything after that to not show up. I am assuming there is an error of some sort, but I am not sure how to display the error. Here is my code: <?php // example of Auth_HTTP implementation with encrypted password and multiple columns fetch require_once("Auth/HTTP.php"); $AuthOptions = array( 'dsn'=>"mysql://user:pass@localhost/auth", 'table'=>"tbl_auth", 'usernamecol'=>"username", 'passwordcol'=>"password", 'cryptType'=>"md5", 'dbFields'=>"*" ); $a = new Auth_HTTP("DB", $AuthOptions); $a->setRealm('yourrealm'); $a->start(); $a->setCancelText('<h2>Error 401</h2>'); if($a->getAuth()) {

    echo "Hello $a->username welcome to my secret page <BR>";
    echo "Your details on file are: <br>";
    echo $a->getAuthData('userid');        // retriving other details from the database row
    echo $a->getAuthData('telephone');      // in this example the user id, telephone number
    echo $a->getAuthData('email');        // and email address

}; ?>
