title: Restrict access to certain TeamCity projects
body: <p>We have a TeamCity instance with a variety of projects and build configurations on it, with no security set up at present. Although it's OK for most of the projects to be publicly visible, we'd like to set up a couple of projects that are only visible to certain users.</p>
  
  <p>Because there are many public projects already set up on the server, across a variety of teams, we'd like to avoid setting up restrictions on everything - that is, we'd rather use "deny access to project Z" than "allow access to project A, allow access to project B, ..., allow access to project Y".</p>
  
  <p>How can I restrict access to these projects without affecting the public projects?</p>
