I am having a problem with a shared folder in R2. I create a share and configure it the way i always do. So i right click the folder and click on the Sharing tab and set the everyone group full control. I do this because i know that i can lock that folder down using the Security tab via NTFS permissions.
So no i click Security and add in my group of users who i want read only access to on this share.
when testing this setup logged in as a member of the read only group it still allows me the create folders and files in the share so basically ignoring the NTFS perms.
