How To Make All Reports On SSRS Location Specifically

I am trying to make all reports on SSRS location specific. e.g I only people who work in certain locations will be able to view certain parameters.

I figured that I can do this using User!User.ID and an access control list. I have tested this by manually creating a sample ACL but I want to be able to automatically populate the list with data from AD.

I can find lots of stuff online that allowed me to extract information from AD but I cannot see a way of creating a full list which includes memberships.

e.g:-
USERNAME MEMBER OF
User1 location1
User1 location2
User1 location3
User2 location1
User2 location4

I am able to get users by specifying a group and getting memberships by specifying a user but I am not able to get a full list.

i have created a ADSI link server.
