[Plugin: WP Sliding Login/Dashboard Panel] Login doesn't work

When I login, I get a 404 not found error.
After the login the user gets redirected to http://www.domain.com/wp-admin

My wp is installed in /wp/wp-admin, so the redirect should go to http://www.domain.com/wp/wp-admin.

Any suggestions?

Cheers
