Multiple extended responses per request

[Dave Wilbur <DWILBUR@novell.com>]

While developing an LDAP v3 extension, a developer here wanted to be able to send multiple responses against one request.  This was relatively easy to support in our server code, but the published client APIs don't support more than one response per message id.  While RFC 2251 for LDAPResult is quite clear in stating "to indicate the *final* status of a protocol operation request", the ExtendedResponse is not quite so definitive: "The server will respond to this with an LDAPMessge containing the ExtendedResponse."

Given the precedent of an interim response in the Search verb as well as Persistent and Triggered search, it seems to make sense that an Extension might want to do this as well.  We were going to use different OIDs to indicate if a response was interim or final until we ran into the client issue.

Is this feasible? reasonable?

Looking for feedback.
