0.2.0: The Winter Roll-up 
i have basically touched every file help

* Moved all the error code stuff to one new sectional page, because the old way of doing it sucked big time.
* Rename passport (soap) to RST
* Formatting changes (many)
* Several corrections
* change git host because git.kevinthe.horse seems Dead

Introduction

The Passport Request Security Token (RST) service, or "Passport 3.0" as it's sometimes called, is a HTTP-based authentication system that was introduced with MSNP12.

The endpoint is called RST.srf, residing on either the login.passport.net or the login.live.com domain.

For MSNP8 to MSNP11, read the Passport 1.4 article.
For MSNP18 and above, read the Request Security Token service, version 2 article. (TODO: Write this, and did I get this right?)

Client/Request

The following sub-headers are XML elements for the client's request.

  1. <wsa:Address>: By URL or domain name
  2. <wsa:ServiceName>: By service name

wsa:Address

This element contains the target domain for this security token:

  • http://Passport.NET/tb: Legacy authentication, One of these is always required (usually as RST0). Does not set a <wsse:PolicyReference>.
  • messengerclear.live.com: The domain used for solving MBI_KEY_OLD challenges. Uses a policy defined by the MSNP server, which is usually MBI_KEY_OLD.
  • messenger.msn.com: The usual domain for authenticating to the Messenger Service. Uses passport unique parameters (?...) defined by the MSNP server, or ?id=507 if using messengerclear.live.com to authenticate.
  • contacts.msn.com: Used for the Address Book Service. Uses passport unique parameters (?...) or MBI (since MSNP15). Required since MSNP13.
  • messengersecure.live.com: A secure version of messenger.msn.com, with unknown use. Uses MBI_SSL.

This optional element has only one attribute:

  • URI: The security policy of this security token:

    • MBI_KEY: Unknown, but probably not unlike MBI_KEY_OLD?
    • MBI: No special parameters.
    • MBI_SSL: No special parameters and encrypted transport only.
    • MBI_X509_CID: Unknown, but based on user certificates. Only used with p2pslc.messenger.msn.com.
