Hello to everyone 
We have one basic Customer pointing Service desk project that all of ours clients can create issues. Now we are planning to add another Customer Service desk project that serve only to approved Corporate clients to submit issues to us. The problem is when the approved corporate customer is logged into the system, he can see both Service desk projects. How can we hide the basic customer service desk project?
After basic research we saw, this is a basic functionality for Cloud, but for on-premise it isn't! ? Any idea how deal with the problem !?
