wp_signon redirect

I am using wp_signon to create a login form. My problem is that on successful login the user is directed to wp-admin which I do not want.

I thought that wp_signon returned an object but did not divert to wp_admin. This is the way it works on failure but on success the user is taken to wp-admin.

$creds['user_login'] = $_POST['username'];
    $creds['user_password'] = $_POST['userpassword'];
    $creds['remember'] = true;

    $user = wp_signon( $creds, false );

    if ( is_wp_error($user) )
      echo $user->get_error_message();

The code is pretty much taken from the codex ( yes I know I could use the post variables direclty) So really do not understand why 🙂

Thanks in advance….
