First, the paragraph that spawned this post:
\nThe increasing use of cloud-based services is driving the need for better and more interactive single sign-on (SSO) and federated identity management (FIM) services. It is building relationship dependencies between businesses, their partners and suppliers, and customers.
\n— Ovum Research, “Cloud: Transforming the IAM Industry”
\nFirst, I beg to differ on the conclusion that cloud is “transforming” the IAM industry. It’s pretty much the same as it’s ever been. Single-sign on (SSO) is still about protocol transitioning; it’s just the case that protocols have been abstracted into APIs. Federated Identity Management (FIM) is SAML wrapped up in a nice name. This is not transformational. Organizations have been integrating authentication and authorization across the Internet since after the dot com bust. XML gateways, anyone? WS-SEC? Seriously, this is not transformational. At best it’s evolutionary.<\/p>\n
