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); : $imap->logout; ntlm_reset; : or ntlmv2(1); ntlm_user($username); ntlm_host($host); ntlm_password($password); : or 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. FUNCTIONS ntlm_domain() Set the domain to use in the NTLM authentication messages. Returns the new domain. Without an argument, this function returns the current domain entry. ntlm_user() Set the username to use in the NTLM authentication messages. Returns the new username. Without an argument, this function returns the current username entry. ntlm_password() Set the password to use in the NTLM authentication messages. Returns the new password. Without an argument, this function returns the current password entry. ntlm_reset() Resets the NTLM challenge/response state machine so that the next call to C<ntlm()> will produce an initial connect message. ntlm() 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. ntlmv2() Use NTLM v2 authentication. OBJECT API new %options Creates an object that accepts the following options: "user", "host", "domain", "password", "version". challenge [$challenge] If $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.
