[Zope-PTK] Missing function in Membership.PersistentUser

[Fabio Forno]

Hi,
when using the membership system it's impossible to get the users'
roster, because the Portal.getRoster() calls the getUsers() and that
function is missing.
At present I've solved that problem addind this python method in the
UserSource:

getUsers(self):
 user_ids=self.getPersistentItemIDs()

 users=[]
 for i in user_ids:
   users.append(self.getItem(i))

 return users 


ByE,
