title: User Permissions - SharePoint 2013 Central Administration page and Sub-Site page
body: <p>I have installed SharePoint 2013 Foundation in a 2 server farm topography. I am trying to create a sub-site for normal authenticated users and keep the Central Administration root site for only the SP admins. When I create a sub-site I think I am adding a user group and users to that site, for access to only that site, but users in that group can still see the Central Administration site. I need to assign separate permissions on each site. Is there a tutorial or something out there that can help a beginner do this?</p>
