Setting registry BasicUserAuthenticationLevel to 2 during OXConnector Install

This is not an error or a bug. This is an expected behaviour if a customer want to use Infostore functionality, then OXUpdater has to adjust the registry by changing BasicUserAuthenticationLevel to value 2. Otherwise connecting to WebDAV will fail.
