Some user information, configuration and preference information is stored in LDAP, to which users may not have access at all -- direct or via the Web Administration Panel.
This may include;
- Personal phone number,
- Photo,
- Invitation Policy,
- Spam preferences,
- etc.
In the particular case in question, a user is a group manager's account member user, and therefore is not provided access to the #hkccp.
However, the group manager in question may wish for its member users to be provided with an option to upgrade from the default "Lite" account to a better and shinier "Pro" account type (and perhaps downgrade as well).
The first iteration for the plugin in question could hold an upgrade and a downgrade button;
A first few set of profiles would be;
- Email only, "Lite", 2GB static,
- Full groupware + ActiveSync, "Pro", 10GB static.
This means the user (group manager account's member user) will need to be able and allowed to change nsroledn and mailquota attribute values.
