   2. In the left pane, expand Authentication » SecurityTokenService » AuthenticationProviders » WindowsAuthentication. 
      
   3. In field Metadata Address, enter your WindowsAuthWebHost address.
      For example, enter https://localhost:893 
      
   4. Select Enabled checkbox and save your changes.
      
4. Setup LDAP settings in the following way:
