We have a requirement that need to restrict multi browser login with same user into SharePoint. We have 2 AD, 1 for external user and 1 for internal user. Our SharePoint site was integrated with AD. When the user accessing the portal, they will be redirected to AD home page to choose the AD. Once they choose the AD option, they will be redirected to appropriate AD login page. After validate, they will be redirected to SharePoint Home Page.
We need to implement once the user session established, we should not allow the user login from another browser. Please guide how to implement this functionality.
