Heimdal NTLM library

1.5.2

Introduction

Heimdal libheimntlm library is a implementation of the NTLM protocol, both version 1 and 2. The GSS-API mech that uses this library adds support for transport encryption and integrity checking.

NTLM is a protocol for mutual authentication, its still used in many protocol where Kerberos is not support, one example is EAP/X802.1x mechanism LEAP from Microsoft and Cisco.

This is a support library for the core protocol, its used in Heimdal to implement and GSS-API mechanism. There is also support in the KDC to do remote digest authenticiation, this to allow services to authenticate users w/o direct access to the users ntlm hashes (same as Kerberos arcfour enctype keys).
