Create groups as if by super

Project Description
Introduction
============

This is a PAS plugin that makes it possible to create groups "on the fly" for
users via subscription adapters and utilities.

The plugin can be installed using a GenericSetup extension profile.

For example, say you have an LDAP repository where a user property contains a
user's business unit. If this is mapped as a user property, you can write a
subscription adapter that adapts the user to ISuperGroups. It would look up
this property on a user and return a list of group ids that corresponds to the
value of the property. When Plone lists a user's groups or assigns roles based
on a user's groups, the user will appear to be a member of this group.

For example::

from zope.interface import implements
from zope.component import adapts

from borg.supergroup.interfaces import ISuperGroups
from Products.PluggableAuthService.interfaces.authservice import IBasicUser

class ImpliedGroups(object):
implements(ISuperGroups)
adapts(IBasicUser)

def __init__(self, context):
self.principal = context

def __call__(self):
implied = self.principal.getProperty('implied_group', '')
if implied:
yield implied

This can be registered in ZCML with::

<subscriber factory=".groups.ImpliedGroups" />

This is a simple example that looks for an implied group in the
'implied_groups' user property. Of course, you could source the group(s) from
wherever you want. The return value should be an iterable (here we use a
generator).

To make implied groups show up in general group listings (e.g. on the
'Sharing' tab in the Plone user interface), you could write a named utility
providing ISuperGroupsEnumeration. This will be passed some search parameters,
and should return any implied groups if they can be matched to the search
parameters.

For example::

from zope.interface import implements
from zope.component import adapts

from borg.supergroup.interfaces import ISuperGroupsEnumeration

class ImpliedGroupsEnumeration(object):
implements(ISuperGroupsEnumeration)

def enumerate_groups(self, id=None, exact_match=False, **kw):
if (exact_match and id == 'Alpha') or (not exact_match and id in 'Alpha'):
yield dict(id='Alpha', title='Alpha Group')

In ZCML, this would be registered with::

<utility
factory=".groups.ImpliedGroupsEnumeration"
name="my.implied.groups"
/>

For more examples, see the tests in integration.txt and the interface
declarations in interfaces.py.
