1. Purpose
The protocol specification for SOCKS Version 5 specifies a
generalized framework for the use of arbitrary authentication
protocols in the initial SOCKS connection setup. This document
provides the specification for the SOCKS V5 GSS-API authentication
protocol, and defines a GSS-API-based encapsulation for provision of
integrity, authentication and optional confidentiality.
2. Introduction
GSS-API provides an abstract interface which provides security
services for use in distributed applications, but isolates callers
from specific security mechanisms and implementations.
GSS-API peers achieve interoperability by establishing a common
security mechanism for security context establishment - either
through administrative action, or through negotiation. GSS-API is
specified in [RFC 1508], and [RFC 1509]. This specification is
intended for use with implementations of GSS-API, and the emerging
