K2 Five Roles not resolving AD Groups to Users

Hi

I have K2 Roles that we use to easily manage the Users in the application. I have added AD Groups to these roles rather than to add a bunch load of users manually. Now, i send out Tasks as well as Emails to these roles by using the Role or "Get Role Users" respectivly to actually get these out to the users.

Firstly , Tasks are not assigned to Users in AD Groups (it does send out to indivual users)

Secondly, When Executing the User Role or URM User Smart Objects, i do not get the users that are in these AD Groups. However, in some situations SOME AD Users from the AD Groups will show up in the  URM User.

Is there a setting perhaps on the K2 Five Server that allows these AD Group Users to be resolved? Am i Missing something?

I have found this:
