Use Basic
restart the service, and change the username format to DOMAIN/USERNAME
or remove the doman and use USERNAME
also try USERPRINCIPALNAME

you need to now setup the connectivity logging to find out what happen

I will also use a 3rd party like thunderbird to try this to work out what happen on the password.
