Today, the eagerly expected FIM2010 R2 release was made available on TechNet and MSDN. I couldn't find a trial version in the usual locations, but I guess those will be released in the days to come. To discover what is new, you can check the TechNet library, which has a lengthy discussion of everything new and improved. Of course, you can also check my earlier post on this very subject.
A nice surprise came in the form of what is now called the Microsoft BHOLD Suite, IP that Microsoft acquired in September 2011 from the former BHOLD company, that is now renamed into "Elephant Security". You can find this as well on TechNet, MSDN, etc. With this addition, Microsoft are now able to offer a complete RBAC solution. The Microsoft BHOLD Suite is documented here.
