How about the use of the term "TLS-protected LDAP connection"?
TLS is not protecting the underlying connection, it's protecting
the exchange of LDAP messages.

And, is the association really at the underlying connection or
at the LDAP exchange?

In processing a bind, the spec says "to bind on the existing
connection" when the Bind, when TLS or SASL have been establish,
certainly is done on the underlying connection.
