Bert,
Thank you for the response. I ended up having a class level method that
creates the connection, where I pass the server name, password, etc. And
then another class level method to access the ldap connection, which the
instance level methods call. So in pre-fetch I create the connection, and I
can directly access the ldap connection in self.instances. But create and
destroy makes a call to the 'accessor' method.
Thanks
Len
