Force synchronization of AD users and groups


Can I force the synchronization of the membership of users to AD groups from Rockstor?

I have installed Rockstor 3.9 1.0 and the case is that I manage the permissions through Active Directory and when I modify permissions from Windows on the shared directories in Samba, if the change is of a user it becomes effective at the moment, but when the change is related to add a user to the group that enables access, the change takes hours to become effective and therefore the user takes hours to be able to access the resource.
