Products.SimpleGroupsManagement 0.4.1

A Plone utility that let non-Manager users able to manage some (specific) groups


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 playing with the (Plone Site Setup: Users and Groups). Even playing with this permission is impossible to limit the group on which a member (or group) can manage.

This products and 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


where id1, id2 can be user or group ids. This mean that those subjects will be able to act on groups.

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 or removed, an event is notified.


Tested with Plone 4.2 and 4.3. Look for older releases if you need Plone 3 compatiblity.

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 still protected by the Use Simple Groups Management permission (commonly given to all site Members).
