3.1.6.3 dnsRecord in the Directory Server

If the server is directory server integrated, then whenever dnsRecord attribute values (section 2.3.2.2) are written to the directory server by using LDAP, each string MUST be converted from type DNS_RPC_NAME (section 2.2.2.2.1) to type DNS_COUNT_NAME (section 2.2.2.2.3). Similarly, when reading dnsRecords, the DNS server MUST convert each string of type DNS_COUNT_NAME to type DNS_RPC_NAME.
