Understanding the Terminology

systems and the Microsoft implementation uses a DNS lookup to resolve host names. But both implementations are written to RFC 1510 (The Kerberos Network Authentication Service (V5)) and RFC 1964 (The Kerberos Version 5 GSS-API Mechanism), and hence they can interoperate.

Table 4-1 summarizes analogous terminology in the Kerberos server and Windows 2000 Kerberos implementations.
