The purpose of this module is to perform a user authentication via Microsofts NTLM protocol. This protocol is supported by all versions of the Internet Explorer and is mainly useful for intranets. Depending on your preferences setting IE will supply your windows logon credentials to the web server when the server asks for NTLM authentication. This saves the user to type in his/her password again.

The NTLM protocol performs a challenge/response to exchange a random number (nonce) and get back a md4 hash, which is built from the users password and the nonce. This makes sure that no password goes over the wire in plain text.

The main advantage of the Perl implementation is, that it can be easily extended to verify the user/password against other sources than a windows domain controller. The defaultf implementation is to go to the domain controller for the given domain and verify the user. If you want to verify the user against another source, you can inherit from Apache2::AuthenNTLM and override its methods.

To support users that arent using Internet Explorer, Apache2::AuthenNTLM can also perform basic authentication depending on its configuration.

IMPORTANT: NTLM authentification works only when KeepAlive is on. (If you have set ntlmdebug 2, and see that there is no return message (type 3), check your httpd.conf file for "KeepAlive Off". If KeepAlive Off, then change it to KeepAlive On, restart Apache, and test again).
