Perspective project properties “Permissions” group set to Public->Authenticated->Roles->Operator
Login with user without Operator role.
Page shows with “Forbidden” and cannot go back to login as another user (it just auto-logs back in as the same user). Browser must be closed and reopened.
Thanks for reporting this. We lack a button or link on that page to logout (if you are already logged in). I’ve created feature ticket 14512 to address this.
