The big news in the Identity & Access Management (IAM) world today is Oracle's acquisition of Passlogix. In fact, I made the observation 2.5 years ago (when talking about IBM's acquisition of Encentuate) that the most logical suitor for Passlogix was indeed Oracle.
It was only a matter of time, but I'm surprised it's taken Oracle this long to officially add enterprise single sign-on (ESSO) to their suite. I use the word "officially" because Oracle's long-standing OEM agreement with Passlogix means customers are unlikely to see much change in the short term. It simply means Oracle will officially own the technology powering their ESSO product instead of having to "repaint" it red & white. You might also see quicker turnaround times in getting your queries answered and your support calls resolved, so I suppose that's a plus.
Congratulations to all the Passlogix gals and guys.
