Thanks Jeff, I have a follow-up.
I'd like to be able to give two users with different group assignment a different view of a single folder, i.e. in a folder there are 2 files, one which has Group A cmis:read, the other which has Group B cmis:read. Therefore a user from either Group A would only see a single file, the same is true for Group B, except it would be the other file. From what I can tell that's not possible with the current permissions mapping in Alfresco, and perhaps not at all within the bounds of CMIS. Can you advise?
MTIA.
