 The Gitblit JSON RPC mechanism, like the Gitblit JGit servlet, syndication/feed servlet, etc, supports request-based authentication.  Making an *admin* request will trigger Gitblit's basic authentication mechanism.  Listing of repositories, generally, will not trigger this authentication mechanism unless *web.authenticateViewPages=true*.  That means its possible to allow anonymous enumeration of repositories that are not *view restricted* or *clone restricted*.  Of course, if credentials are provided then all private repositories that are available to the user account will be enumerated in the JSON response.
