Products.SimpleGroupsManagement 0.3.1

A Plone utility that make possible for non-Manager users to manage some (specific) groups

Introduction
============

Have you ever feel the need to give to normal (AKA: not Manager/Site Administrator ) Plone member the power to
manage a group?

Right now in Plone you can make this possible playin with the **Manage users** and **Manage Groups**.

Even playing with those permissions is impossible is to limit the group on which a member (or group of members)
can manage.

This products make something very dangerous: with a minimal configuration, a member of the Plone portal
(or all members in a group) will be able to manage the users of a group overriding the basic portal security.
You only need to go to the *portal_properties* tool of you portal and modifiy the new
**simple_groups_management_properties**.

In the *sgm_data* section you need to insert a set of strings like

::

id1|group_id1
id2|group_id2
...

where *id1*, *id2* can be user or group ids. This mean that the member (or group) id1 will be able to act on the
group_id1 members.

You can also insert a list of groups ids that will be never handled by this product in the
**sgm_never_managed_groups** section.

The utility also react to the **Add portal members** permission. If the current user has this permission
you will be able to add new portal members (so no security break for this).

When an user is added to a group or removed, an event will be raised.

Be aware!
---------

This products override all normal Plone permissions noted above! This can create **security black-holes** in
your portal!

The access to the new user/group management form is protected by the **Use Simple Groups Management**
permission (commonly given to all site Members).
