active directory share folder

Dear All

i have to create a sharefolder on the network

i have a domain controller with AD

and a file server

so i create a folder , share it on my fileserver

then in AD i create a sharefolder and gave the path that i created in my fileserver.

but i would like to manage the access to that sharefolder from my AD 

on the properties on the sharefolder in AD  i only have  general and managed by 

i can set the user who can manage it but i tried to set a user who can manage the folder.

i would like to let all the users of my OU to access that sharefolder cause i have created that sharefolder in the specific OU.

when i log with a user that does no belong to the OU where i create the sharefolder he can access the sharefolder 

normally i should have a security tab in the properties of that sharefolder to manage the permission i dont have it

can someone explain please?

thanks
