I've setup our internal Adobe Update server back with CS6 and rebuilt it with the 3.0 tool for CC Enterprise. Our PC users are able to poll the server and get updates, but our Mac users report back that there are no updates for them. For the mac users this happens with the Adobe Application Manager, and for the folks with Creative Cloud, we've been trying to use the Remote Update Manager, that spits a Report 0 message. In the logs it claims that there appear to be no updates. I've made sure that our URL in the AdobeUpdater.overides is correct, and you can load the page as expected in a browser. I've also put in a bad address purposefully to make sure that the error message would be different if it couldn't reach the server. When it's incorrect it correctly reports just that. So I know it's talking to the server, but It's not getting correct info back.
The server is running on a Mac, running 10.7.5 server, at the latest security patch level. I've rebuilt the AUServer, and even changed paths and updated the overide files, but our Macs still report back that there are no updates available for them. If I remove the Overides file, the macs will talk with the official Adobe server and download updates directly, so I think it's something with the AUS. Thoughts?
