Private project status overrides regular project access rules in SLIM-Collaborate to restrict access to a project to only those users explicitly granted access. Unlike regular projects, private are not automatically visible to Site Administrators. Normally, site admins are the only users who can see every project in the portfolio, regardless of project-level access settings. This ensures that there is always at least one user who can see and access all projects, providing global oversight of the site’s usage and project data. But for private projects, Site Admins will have access to a private project ONLY if the site admin is explicitly designated as the person with Primary Responsibility. Site Admins cannot be added to a project’s user access list, so unless a Site Admin happens to be the user with Primary Responsibility for a project, he or she will not have access at all. Private projects are also not visible to users who belong to the project’s designated OBS Node (or higher nodes if this box is checked on the project’s access tab).
