An NTLM authentication module
This module provides methods to use NTLM authentication. It can
be used as an authenticate method with the Mail::IMAPClient module
to perform the challenge/response mechanism for NTLM connections
or it can be used on its own for NTLM authentication with other
protocols (eg. HTTP).
The implementation is a direct port of the code from F<fetchmail>
which, itself, has based its NTLM implementation on F<samba>. As
such, this code is not especially efficient, however it will still
take a fraction of a second to negotiate a login on a PII which is
likely to be good enough for most situations.
