Authentification failed after SSL enabled

Hi,
When I enable SSL using first method described in this post
http://ithemes.com/codex/page/Fix_Non-SSL_Elements_on_SSL_Page

I am getting “Authentification failed. The user has canceled the authentication or the provider refused the connection. “

I get this error when following rule is added to .httpacess
RewriteCond %{SERVER_PORT} !^443$
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
when I have only define(‘FORCE_SSL_ADMIN’, true); n wp-confin all works good but content is not secured.

Amy idea what could be causing this issue?

Thanks
Regards
Pawel
