Problem with reauth parameter

[Nirzol]

Hello

Problem when access wp-admin directly . WP redirect to wp-login.php with REAUTH=1 parameter.
This parameter kill all cookies...
I already get this prob with my CAS plugin and resolved it with filter.

To solve this , I add a filter into construct to remove this parameter
add_filter( 'login_url', array( $this, 'efg_wp_cas_clear_reauth' ) );

And my function :
/**
* Clear reauth parameter from login url to login directly from CAS server.
* Remove the reauth=1 parameter from the login URL, if applicable. This allows
* us to transparently bypass the mucking about with cookies that happens in
* wp-login.php immediately after wp_signon when a user e.g. navigates directly
* to wp-admin.
*/
public function efg_wp_cas_clear_reauth( $login_url ) {

    $login_url = remove_query_arg( 'reauth', $login_url );
    return $login_url;
}

Hope will help people using this plugin.
