The subject of using SharePoint as an Extranet has come up in conversation a few times recently and I was wondering if the community pursue this option in their Farms? We used a very cool Extranet tool called Extradium on SP24, but I know there are other options out there (such as doing your own Forms Based auth). I am really interested to see how you do it? If you do extend SharePoint to your partners do you go for a completely separate Farm running SP Foundation? We also offer a solution to help manage third-party risk so would love to hear your thoughts on that.
I’ve in the past extended a 2007 webapp to FBA, and used the authentication formerly known as ADAM (now ADLDS I think).
We initially used a user management solution from codeplex (I forget the name), but it had a number of quirks, so it was replaced with a commercial product, whose name also escapes me.
We fronted it all with Microsoft IAG.
