Re: Bye bye
SSO was never implemented because VMWare is like any other large software vendor, acquire technology because it is cheaper than building it, gives a complete "check box" list of features dow a web page.
The main problem with the growth through acquisition is that there is this think called acquisition cost, bringing the products into line with the rest of the software suite, sometimes (most of the time) it costs money to do things to centralize and after digesting a big acquisition keeping money in the bank is more appealing that designing things to integrate the stack better (like SSO), besides one of the fundamental cost savings that is made after any acquisition is reduction in development headcount.
Can't develop new features when you get rid of your team and don't want to spend, I was looking at a product recently name is like "Big flix" owned by IBM and then someone else ...... in one screen we saw behind the 'kimono' - wow, my comment at the time was "Lipstick on a pig". VMWare has been no different for sometime, too big/fat to innovate.
