we haven't add support for the Unsolicited Notification, as specified in RFC 4511, chap. 4.4 :
We had it with the old RFC AFAIK. But are you suggesting this new revision has some aspects we have not implemented and therefore need to re-implement this protocol feature?
4.4. Unsolicited Notification
An unsolicited notification is an LDAPMessage sent from the server to
the client that is not in response to any LDAPMessage received by the
server. It is used to signal an extraordinary condition in the
server or in the LDAP session between the client and the server. The
notification is of an advisory nature, and the server will not expect
any response to be returned from the client.
The unsolicited notification is structured as an LDAPMessage in which
the messageID is zero and protocolOp is set to the extendedResp
choice using the ExtendedResponse type (See Section 4.12). The
responseName field of the ExtendedResponse always contains an LDAPOID
that is unique for this notification.
One unsolicited notification (Notice of Disconnection) is defined in
this document. The specification of an unsolicited notification
- the OBJECT IDENTIFIER assigned to the notification (to be specified
in the responseName,
- the format of the contents of the responseValue (if any),
- the circumstances which will cause the notification to be sent, and
- the semantics of the message.
4.4.1. Notice of Disconnection
This notification may be used by the server to advise the client that
the server is about to terminate the LDAP session on its own
initiative. This notification is intended to assist clients in
distinguishing between an exceptional server condition and a
transient network failure. Note that this notification is not a
response to an Unbind requested by the client. Uncompleted
operations are handled as specified in Section 3.1.
The responseName is 188.8.131.52.4.1.1466.20036, the responseValue field
is absent, and the resultCode is used to indicate the reason for the
disconnection. When the strongerAuthRequired resultCode is returned
with this message, it indicates that the server has detected that an
established security association between the client and server has
unexpectedly failed or been compromised.
Upon transmission of the Notice of Disconnection, the server
gracefully terminates the LDAP session as described in Section 5.3.
