liveuser_admin - storing extra data

Hi, I'm trying to add some extra data to the users table. I modified my $conf array by adding this: 'storage' => array( 'dsn' => LIVEUSER_DSN, 'prefix' => 'lu_', 'tables' => array( 'users' => array( 'fields' => array(

				'lastlogin'     => null,
				'is_active'     => true,

'fname' => null, 'lname' => null,

				'org'       	=> null

), ), ), 'fields' => array(

		'lastlogin'     => 'timestamp',
		'is_active'     => 'boolean',

'fname' => 'varchar', 'lname' => 'varchar',

		'org'       	=> 'varchar'

), ), I also added these fields manually to the database. Now I get this error: ["code"]=> int(-4) ["params"]=> array(1) {

    ["reason"]=>
    string(33) "field may not be empty: is_active"

} ["package"]=> string(14) "LiveUser_Admin" ["level"]=> string(9) "exception" ["time"]=> float(1129203367.4792) ["context"]=> array(4) {

    ["file"]=>
    string(56) "/usr/local/share/php/pear/LiveUser/Admin/Storage/SQL.php"
    ["line"]=>
    int(147)
    ["function"]=>
    string(6) "insert"
    ["class"]=>
    string(26) "LiveUser_Admin_Storage_SQL"

} ["message"]=> string(68) "Couldn't create the query, reason: field may not be empty: is_active" } Looking at my conf is_active should just default to TRUE.. Jeroen
