Message boards security

Message board

Based on the Access and Message board owner properties of the Message board web part, you can determine who will be allowed to add new messages to the board.

Changing the values

Remember that once the message board is created (after inserting first message or subscribing), you cannot make changes to these settings in the New board settings section of web part properties. You can only modify values of the Access property on the Security tab when editing the corresponding message board in the Message boards application.

The following table explains who can add messages to the board under particular configurations. The difference between User and Public boards is that Public boards are always related to a page, while User boards are always related to a page and a user.

Public boards are typically used when you want multiple users to post messages to it. User boards are typically used on user profiles, as you can see on the Community starter site sample website, on the Members -> Profile page.

When a board is in the User x Owner configuration, the following conditions need to be met in order for the current user to be able to post messages:

  • the page must be accessed with userid or username parameter in querystring
  • the current user must be the same as the one whose userid or username is passed in querystring
  • the current user must not be hidden (configured by the Is hidden option when editing the user)

This can be typically used on user profiles, where messages to such board can be posted only by the owner of the profile, while other users can only read these messages. An example of such board is the MessageBoardAnnouncements board on the /Members/Profile page of the sample Community Site.

Group message board

The Group message board is always related to some group, hence only the Access property can be set. You can see a typical usage of this web part on the Community starter site sample website, on the Groups -> Profile page.

When the Group members option is set, the following conditions need to be met in order for the current user to be able to post messages:

  • the page must be accessed with groupid parameter in querystring
  • the current user must be member of the group whose groupid is in the querystring
  • the current user must not be hidden (configured by the Is hidden option when editing the user)

This can be typically used on group profiles, where messages to such board can be posted only by members of the group, while other users can only read these messages. An example of such board is the GroupMessageBoard board on the /Group-pages/<group name> page of the sample Community Site.

Permissions

Permissions for access to Message boards administration interface can be set in the Permissions application. You have to select the Modules -> Message boards permission matrix.

  • Modify - members of the roles are allowed to edit message board settings, delete the boards and manage message board posts
  • Read - selected role members are allowed to read the records and configuration of particular message boards, but are not allowed to modify them
