Ad group not assigned

Hello experts,

(Ver 7.1.2)

We have an active directory group that is not being assigned as we expected.

 

We have a Service item published in the IT shop that has an Active directory group associated. Whenever an employee requests it and the approval workflow is completed, the item is correctly assigned… But the AD group isn’t.

We have checked that the “Groups can be inherited” checkbox of the ad account is enabled.

 

Is there a configuration parameter or something that should be enabled in order to behave as we described?

 

Thanks in advance.
