Two factor auth on 4.x-dev w/ LoginLdap fails currently due to the confirm password workflow. The code will try to use the current login plugin's twig template for
confirmPassword (since custom login controllers must inherit from Login's Controller). Usually this isn't defined.
This change forces use of
<a class='mention' href='https://github.com/Login'>@Login</a>/confirmPassword and sends the request to the currently configured Login plugin. Tested with LoginLdap using an LDAP user and it appears to work.
