SOA, NS, and A records work alongside SRV records to provide service resolution used during KDC discovery and other domain controller operations. By adding SRV support, we can begin to use ApacheDS as a realm controller.

Adding a resource record (RR) to Apache DNS involves the following steps:
1) Add a new objectClass and possibly attributeType support to the apachedns.schema for the new RR type.
2) Write an Encoder that knows how to convert from the RR attributes to the binary resource data payload in the DNS reply.
3) Add the RR type-to-Encoder mapping to the DnsEncoder's hashed adapter.
4) Add example SRV record(s) into the LDIF that ships with the DNS protocol provider.

Support for serving SRV records has been added.
o In addition to the above steps I also added the attributeTypes to the DnsAttribute constants.

Committed to apacheds-core (apachedns.schema) on revision 292329.
