Hi Eduardo,
For some reason this part of the documentation has been lost. I will try to recreate it in the near future. In short you need to do the following;
To login:
Open the Login action of the Common -> Login page. Change it so it looks like this;

The GetOAuth2AuthenticationURL is from the Microsoft Login Connector. The output of this action is used in the RedirectToUrl widget. This will enable the login action.
To logoff:
Open the ClientLogout action from the Common -> UserInfo block. Change it so it looks like this;

The output if GetOAuth2LogoutURL is used int he RedirectToUrl widget.
I hope this helps.
Greetings,
Vincent
