I have created a subsite, where I have kept the inheritance from the parent site.
But what I would like to do is to create several document libraries where I stop the inheritance of the parent/sub site.
It is not an issue to stop the inheritance. But when I open the document library, press Library Setting, Permissions for this document library and then grant permissions to one AD group it gives the same permissions for the entire subsite.
I have tried to follow the instructions on the Microsoft TechNet - although they only have a description for SP2013 which isn't quite the same - can anybody please tell me what I'm doing wrong?
Problem solved - but thanks for comments. I created a new group for the subsite with the proper permissions, then after stopping the inheritance for the library I deleted all the other groups with AD groups in them, and added the AD group I wanted for the new group. Now I just need to test if I have to make a new group for each of my different libraries...
