Authen::NTLM - An NTLM authentication module
use Mail::IMAPClient; use Authen::NTLM; my $imap = Mail::IMAPClient->new(Server=>'imaphost'); ntlm_user($username); ntlm_password($password); $imap->authenticate("NTLM", Authen::NTLM::ntlm); : $imap->logout; ntlm_reset; :
ntlmv2(1); ntlm_user($username); ntlm_host($host); ntlm_password($password); :
my $ntlm = Authen::NTLM-> new( host => $host, user => $username, domain => $domain, password => $password, version => 1, ); $ntlm-> challenge; : $ntlm-> challenge($challenge);
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.
Set the domain to use in the NTLM authentication messages. Returns the new domain. Without an argument, this function returns the current domain entry.
Set the username to use in the NTLM authentication messages. Returns the new username. Without an argument, this function returns the current username entry.
Set the password to use in the NTLM authentication messages. Returns the new password. Without an argument, this function returns the current password entry.
Resets the NTLM challenge/response state machine so that the next call to C<ntlm()> will produce an initial connect message.
Generate a reply to a challenge. The NTLM protocol involves an initial empty challenge from the server requiring a message response containing the username and domain (which may be empty). The first call to C<ntlm()> generates this first message ignoring any arguments. The second time it is called, it is assumed that the argument is the challenge string sent from the server. This will contain 8 bytes of data which are used in the DES functions to generate the response authentication strings. The result of the call is the final authentication string. If C<ntlm_reset()> is called, then the next call to C<ntlm()> will start the process again allowing multiple authentications within an application.
Use NTLM v2 authentication.
Creates an object that accepts the following options:
$challenge is not supplied, first-stage challenge string is generated. Otherwise, the third-stage challenge is generated, where
$challenge is assumed to be extracted from the second stage of NTLM exchange. The result of the call is the final authentication string.
