If you get an error message when you try to connect that the system cannot load the Microsoft.IdentityModel assembly then you need to install the Windows Identity Framework (WIF) then re-start the application for the changes to take affect.
To enable this feature in Windows type the following into a command line:
dism /online /Enable-Feature:Windows-Identity-Foundation.
When using Windows or Windows server you will need to enable the feature from the
Add/Remove Features utility.
