Windows server 2012 shared folder

I'm new to Win Server 2012. I'm trynashare a folder. In the options, I only want to set the "Sharing Autorisations" but not the "Security" permissions. From what I read on technet, this should only give sharing autorisations to users that try to access to the file over the network ie in the same domain. My problem is that for example : - I give to "All" the read permission in "Sharing Autorisations" - I don't set ANYTHING for "All" in the "Security" tab of the folder.

Result : Users can't enven acces the folder.

What's going on ?

The user must be member of the share permission AND the NTFS security permission.

You can remove ALL users, but your user must be there, with a group or directly in it somehow.

It's like having a house with a alarm system in it, even if the user can enter the house with a copy of the key, if you don't give him the alarm system code, he's toast anyhow.
