Erlang client for NTLM Authentication and NTLM Over HTTP

Client-side implementation of:

• NT LAN Manager (NTLM) Authentication Protocol [MS-NLMP]
• NTLM Over HTTP Protocol [MS-NTHT]

This enables Erlang implementations to interface Microsoft SharePoint and other Microsoft Internet Information Services (IIS) based applications. Few sample functions are provided for interfacing the SharePoint 2013 REST API.

Usage

NT LAN Manager (NTLM) Authentication Protocol

negotiate() -> NegotiateMessage

Constructs the NTLM NEGOTIATE_MESSAGE:

• NegotiateMessage = binary()

authenticate(Workstation, DomainName, UserName, Password, ChallengeMessage) -> AuthenticateMessage

Parses the NTLM CHALLENGE_MESSAGE and constructs the NTLM AUTHENTICATE_MESSAGE:

• Workstation = workstationstring()
• DomainName = domainstring()
• UserName = httpc:userstring()
• Password = httpc:passwordstring()
• ChallengeMessage = binary()
• AuthenticateMessage = binary()

NTLM Over HTTP Protocol

ntlm_httpc:request(Method, Request, Credentials) -> {ok, Result} | {error, Reason}

Replacement of httpc:request that supports NTLM authentication:

• Method = httpc:method()
• Request = httpc:request()
• Credentials = {workstationstring(), domainstring(), httpc:userstring(), httpc:passwordstring()}
• Result = {status_line(), headers(), Body}
• Body = binary()
