How to deny access to Central Administration in SharePoint 2010 for sample user?
If you added the
All auth user group into the SharePoint Central admin then it will give the access to all users.
You can go Central admin > Site Actions > Site Permissions. You will see 2 groups over here
- Delegated Administrators with Contribute Permission
- Farm Administrators with Full control.
Make Sure Only authorized user added here. By default farm admin / Install account is added here by setup.
