perl The purpose of this module is to perform a user authentication via Microsoft's 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. Apache2-AuthenNTLM Apache2::AuthenNTLM Apache2::AuthenNTLM::Lock
