Hi,
I am implimenting Nuxeo for my University Library system and I need to have a way to give each campus library who is participating their own workspace/domain/folder/folderish-thing where I can use the "Manage > Access Rights" tab to set the authorized users.
Using the DM, I set up these folders under the "Asset Libray" which I understand to be some sort of folderish domain thing where the stuff from the DAM goes.

I'm using the Nuxeo DAM default [BETA] 1.2.0 (cap-5.7.1) Application Template in Studio.
I modified Project > Listing & Views > Content Views > DAM-Custom Search based on the answer to this question so that it shows the folders I've created inside of the Asset Library.

But I'm not sure where to go from here.
Is there a better approach to accomplish some sort of "group" for each campus. When a user logs in from a campus, I'm going to want them to only be able to see assets they have permissions to work on.
I'm using the shibboleth plugin, but I could not figure out the expression language to create shibboleth groups, so I figure I'll just use the "Manage > Access Rights" tab on some sort of folderish things to add users to the correct "group" -- but I'm not sure this is the right approach.
