/**
* The only time a client will create a IntermediateResponse is when it is
* decoding it from an InputStream. The stream contains the intermediate
* response sequence that follows the msgID in the PDU. The intermediate
* response draft defines this as:
* IntermediateResponse ::= [APPLICATION 25] SEQUENCE {
* responseName [0] LDAPOID OPTIONAL,
* responseValue [1] OCTET STRING OPTIONAL }
*
* Until post Falcon sp1, the LDAP server was incorrectly encoding
* intermediate response as:
* IntermediateResponse ::= [APPLICATION 25] SEQUENCE {
* Components of LDAPResult,
* responseName [0] LDAPOID OPTIONAL,
* responseValue [1] OCTET STRING OPTIONAL }
*
* where the Components of LDAPResult are
* resultCode ENUMERATED {...}
* matchedDN LDAPDN,
* errorMessage LDAPString,
* referral [3] Referral OPTIONAL }
*
*
* (The components of LDAPResult never have the optional referral.)
* This constructor is written to handle both cases.
*
* The sequence of this intermediate response will have the element
* at index m_responseNameIndex set to an RfcLDAPOID containing the
* oid of the response. The element at m_responseValueIndex will be set
* to an ASN1OctetString containing the value bytes.
