We wrote up LogMeIn's AppGuru cloud management service when it launched as a preview release more than a year ago. It has now exited preview and is on general release -- and that means you have to pay for it.
For sites with between 1 and 49 seats, you'll pay $30.90 per seat per year for the basic service. The premium service costs $62.87 a year, though there's an introductory discount price of $41.53 a month. The basic service lets you sync cloud users with corporate directories; the premium version adds discovery tools to identify SAAS services in use, whether those are "official" or not.
