Section 4.3.  But, as discussed on this list before, clarification
of that section was needed to make it clear the purpose of the
Unbind operation is to gracefully terminate the connection and
everything it carries.

This does remove ambiguity and resolves some interoperability issues (i.e. RFC 2251 failed to specify the AuthN state of a protocol session post Unbind).

Correct.   We could even be more precise in that the Unbind
request causes the termination of the LDAP exchange and the
graceful closure of the SASL layer, graceful closure of the
TLS layer, and graceful close of the connection.

This question is ambiguous as there is/was contention as to what
those semantics were.  A better question would be:
  If the Unbind operation is not disconnect operation, what is it?

>If we go back to RFC 2251 semantics (which are underspecified),

Again, ambiguous.   Some would argue that [Protocol] and RFC 2251
are consistent here.   That is, the function in both is to
gracefully terminate the connection (and everything it carries).
