Supervisor mode lets you control who has access to which group. The reasons for providing security on groups are several. One reason, for example, would be if you wanted to allow users to use groups as mailing lists but you did not want unauthorised users to change the members of the mailing list. In this circumstance you would grant read access only to most users.
You can grant access to a particular group in the following way:
Bring up the Group property sheet by clicking the right mouse button on the relevant group in the right hand list and selecting Edit… from the context menu. Select the Access page.
Specify whether this is a private, personal or public group by selecting the appropriate radio button. If you select Private then only the owner of the group will have access to the group. If you select Personal then other users' access to this group and the contents of the group will depend on their general access to the owner of the group. If you select Public, then all users will have full access to the group and its contents.
If you wish to grant access to the group regardless of users' access to the owner, then select the Custom radio button and press the Custom Access… button.
The Custom Access property sheet will be shown. This property sheet provides two pages; the Item Access page and the Contents Access page. The Item Access page lets you specify access of each security profile to the group. For example, if a user is given edit access, using the Item Access page, then, in the case of a group, they may edit the group's name. If they are given delete access, using the Item Access page, then, they may delete the group. The Contents Access page lets you specify access of each security profile to the members of the group. For example, if a user is given change access, using the Contents Access page, then the user may add or remove users from the group.
For each page, select the security profile(s) whose access you wish to change. Specify the required access by checking the appropriate radio button. The settings will take place when you press OK on the property sheet. The access of all local and remote users that have been assigned the selected security profile(s) will change to the new settings.
