Hi,
We have an web application and Where Anonymous access is enabled.
We have around 300+ host header site collections into it. This is multi-tenant farm. Issue is Any domain user can log into any of such site collections though he dont have permission to login into site collection with read permission. Is this something can be controlled within SharePoint 2013 or Any group policy update or any IIS virtual directory permission issue.
We checked permission levels and groups on SharePoint, no clue we found.
Any ideas on this. Any help would be appreciated.
