Changed commands

USR

MSNP15 uses a new authentication method called SSO (possibly for Single Sign-On). The new USR I command syntax is :

USR trid SSO I email@addr.ess

The new server's USR S command syntax is :

USR trid SSO S policy base64-encoded-nonce

The new client's USR S command syntax is :

USR trid SSO S t=mspauth&p=mspprof base64-ciphertext

The USR OK command is the same as in MSNP14. See the SSO page for more information.

Offline Messaging

There has been a change in the way offline messaging works, the few changes are reflected below and are based on Windows Live Messenger 8.1.0178.00 :

Sending an OIM

The SOAP Action URL changed from http://messenger.msn.com/ws/2004/09/oim/Store to http://messenger.live.com/ws/2006/09/oim/Store2 (i.e. moved to the Live.com domain).

For authentication, the SSO algorithm is now used instead of TWN (see Protocols/MSNP/MSNP15/SSO).
