Access to views

New functionality allows you to set limited access to the repository through views.

The repository manager can set up new "access to views" and remove "access to repository tree" to users.

Permissions can be assigned to the user or group.

Other specifications of the authorization can be set in permission on a specific package.

For example, if you have a user or a group access group and one of the views is a package in which a group or user has a ban on access, the view will not be displayed.
