Information on Private User & Custom Group Permissions for Forum Management

In the forum management interface for a forum, you will see two buttons: manage private users and manage custom group permissions.


What's the relationship between the 2 as you can also add a group in the private user management interface?

 
First, a private forum is a forum that is hidden to non private users. In other words, if you mark a forum as "private", you will need to add users/groups to the "Manage Private Users" interface to grant access. Anyone who is not added specifically will not see the private forum.

"Manager Private Users" page: allows you to add users/groups to a private forum in order to access a private forum. Users/Groups are given the default permissions you set in the forum management interface.

"Manage Custom Group Permission" page: allows you to give a user group(s) special permissions for the forum.

Let's see an example

When a forum is marked as private, our system works this way:

If you have user group A on the private user page, you can give them a different permission set by also adding user group A to the custom group permission page. This way, members in user group A can be assigned different permissions from the defaults you set in the forum management interface.

For a private forum, adding a group to the custom group permission page automatically adds the group to the private user page.


So, these two features can work independently as well as together. A non-private forum can have custom group permissions defined, and a private forum can work without any custom group permissions (i.e., private users will inherit default permissions).

    Hi,
    We have a few private forums that have suddenly become publicly visible (without logging in, if you know the url) although they are not listed in the forums list.
    Guests can even post.
    The forums in question are children of another forum (which has the same security settings) but "Allow Parent Settings & Permission to propagate and override own values" is unticked.
    On the Manage Private Users page, there are 3 user groups added, but these have specific members who need to be logged in.
    As a workaround we have found that if the forum is changed to Public,  and the "Member Rights" and "Guest Rights" are set to "No Access". Then it stops people from seeing the page unless they are in one of the private user groups. 
    Are you aware any circumstance where "Mark as Private Forum (hidden to non-members)" 
    I have tried creating a new Private forum not underneath the same parent forum, and this one does work as expected - guests and non private users cannot view it.
    Thanks
    Andy

    Hi Andy,
     
    No, we are not aware of such issue. Did you try changing the forum in question back to Private and see if the problem persists?

    Hi Sam,
    Yes we did try this and it goes back the way it was, people can view and post without logging in. 
    I am going to look in the database and compare the two forums to see what is different, I can only think some kind of permission corruption has occurred.
    Thanks,
    Andy

    Hi Sam,
    I found that in the database in the pdg_hiddenforumids table, all the private forums in question have `type` set to `1` for the guest user (id = -1) and other members who should not be part of these private forums. Even though these are not listed in the interface on the 'Manage Private Users' page.
    Changing this to `0` makes the forum private again.
    I am not sure what caused this. 
    Is there a way to reset and re-evaluate this data to fix the permissions?
    Thanks,
    Andy

    Hi Andy,
     
    Try running this in the SQL Query Window:
    exec spResetHiddenForumTable
    exec spUpdatePrivateModeratorCache

     
    and see if it fixes the issue.
