Last change on this file since ed3ae7e was e6648bf, checked in by Wilmer van der Gaast <wilmer@…>, at 2008-02-17T11:16:01Z
Replaced old MSN Passport (v1.4) authentication code with what's described on http://msnpiki.msnfanatic.com/index.php/MSNP13:SOAPTweener . This was an attempt to fix bug #360, but it didn't. However, this change may make BitlBee a little bit more future-proof. Plus, the code is tidier and sometimes faster than the old mechanism.
