I read about the concept of interceptors but could not find the detail if they can be activated when a search is carried out. My intention is to collect data from multiple (non-LDAP) sources and make them accessible via a LDAP interface. Because only a changing fraction of the data is needed every day and I can't tell in advance which is needed I don't want to load all of the data into the LDAP. The idea is to intercept the call for "cn=johndoe", search johns data in the mentioned sources / repositories and add if to the LDAP. After that the query can be carried out and the data delivered to the client.
And here are my questions: 1) did I understand the concept of interceptors correctly ? 2) is it possible to intercept searches ? 3) does the interface for interceptors change between ApacheDS 1.5 and 2.0 ? 4) do you see any performance drawbacks in my idea ? Let's assume the retrieval from the sources takes 0 ms, will I experience a delay between importing the data and the point in time when it is retrievable from the LDAP ? Or will it perhaps not be available because of update / caching effects ? Thanks for your input.
