This is the topic which our new white paper, The Case for Using Forms-Based Authentication (FBA) and the SQL Membership Provider for Implementing a SharePoint Extranet, addresses.

The paper can be downloaded from the PremierPoint Solutions website.
An extranet is like an intranet which can be accessed from anywhere on the Internet.
Because the extranet is accessible from the Internet, the need for iron-clad security is paramount. Just as important is the need for users to be able to access and use the extranet easily.
But can both of these seemingly opposing goals really be achieved?
According to the white paper, these ostensibly conflicting goals can be achieved by using FBA and the SQL Membership Provider in on-premises SharePoint.
