Add ability to authenticate against AD/LDAP

[adrianovieira]

Although google authorization is a great feature not all enterprises can use it to grant user authorization for must of their services.

Furthermore, some companies uses AD/LDAP as the service for users and services authentication and authorization.

So, it can be great to have a feature to setup matrix to use AD/LDAP service.

Description

From Wikipedia (AD / LDAP)

• Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services.[1][2] Initially, Active Directory was only in charge of centralized domain management. Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services

• The Lightweight Directory Access Protocol (LDAP /ˈɛldæp/) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.[1] Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network.

I believe the best way to support other kinds of authentication we have to change/decouple the current authentication way to an authentication plugin way.

in this way, anyone can create an authentication plugin to support all kind of authentications:

• Google
• AD/LDAP
• SAML
• Twitter
• Facebook
• Linkedin
• OpenId

Etc..

I'm working on this PR https://github.com/ResultadosDigitais/matrix/pull/235 to improve routes security. After that, the passport.js authentication strategy allow us to implement different auth strategies.

I saw it was merged on PR #303. Does anybody have documented how to use passport.js to auth in matrix?
