I have been working with Sharepoint for awhile but have not yet worked with
Claims Based Authentication. I was hoping to get some advice on the best way to
handle the following scenario. I will have a SharePoint 2010 environment in a
DMZ. This environment will be accessible by both internal employees and various
customers...aka...Extranet scenario. Here is the piece that makes it more
complicated. There are other systems that have databases that house the userids
and other customer information for the individual users that should have access
to the SharePoint environment. We also want to provide Single Sign-On...which
is an extremely important requirement. Based on what I have read, it seems that
Claims Based Authentication with SAML and ADFS would be a good approach however
I am not sure how you use this against the database driven system that has the
user accounts? We could use Claims Authentication with Form Based
Authentication but I was having trouble understanding how Single Sign-On works
in that approach?
