I created an intranet site based on Sharepoint Foundation 2010 which is based on mixed authentication (Windows and Form Based).
It has a main site where all logged users have access and there are different subsites. I am trying to set the subsites in a way that, by default, their access is denied to all logged users.
Users can access to the subsite only if an administrator has granted them access to read or read/write.
Unfortunately I cannot reach the desired result. I have tried to delete the automatically created Visitors group from the subsite but all users continue to have access to the subsite too.
Do you have any idea how can I reach the desired behavior?
