We had SharePoint 2013 farm and integrate with other applications. One of the requirement for integration is disable "Anonymous" authentication for SharePoint portal site. Current web application Claim Authentication Type is Kerberos setup in SharePoint Central admin. We would like to know if change the value from Enable for Anonymous to Disable if:
Any security concerns need to be aware?
Any impacts to SharePoint features/functionalities?
Any MS official documents explain how Anonymous authentication works in SharePoint
Thanks
