def refreshGroupMembership(self, groups):
        """
        This operation iterates over every enterprise account configured in
        the portal and determines if the user account is a part of the
        input enterprise group. If there are any change in memberships, the
        database and the indexes are updated for each group.
        While portal automatically refreshes the memberships during a user
        login and during a periodic refresh configured through the Update
        Identity Store operation, this operation allows an administrator to
        force a refresh.
