Sure, you may subclass the Products.PlonePAS.plugins.user.UserManager class or
any better suited user source plugin class that implements IUserManagement, and
do this :
class ISomeUserDeleted(Interface):
"""Event triggerd at user removal"""
login = Attribute("login that's already successfully deleted")
class SomeUserDeleted(object):
implements(ISomeUserDeleted)
def __init__(self, login):
self.login = login
class MyUserSource(UserManager):
...
def doDeleteUser(self, login):
super(MyUserSource, self).doDeleteUser(login)
notify(SomeUserDeleted(login))
...
With appropriate imports of course. Then handle the "SomeUserDeleted" event in
whatever you want.
Cheers
