GT 4.1.3 GSI-OpenSSH: Developer's Guide

Introduction

This document provides information for GSI-OpenSSH developers.

The changes to OpenSSH to add GSI support are limited, because we build on the existing GSSAPI support in OpenSSH for Kerberos. In addition to adding support for the GSI GSSAPI mechanism, GSI-OpenSSH includes support for GSSAPI key exchange, as specified in draft-ietf-secsh-gsskeyex-08.txt, whereas OpenSSH only supports GSSAPI authentication. Visit the GSI OpenSSH Patch Page for the patch containing the differences between OpenSSH and GSI-OpenSSH.
