I'm using Pidgin on Debian Wheezy, Debian's package version 2.10.6-3. A few days ago I started getting sign-in errors on MSN; specifically, Pidgin complains about Windows Live ID authentication:Invalid response.
Looking at the Pidgin web site, there is a newer version 2.10.7 specifically to fix signin errors with MSN. Unfortunately Debian hasn't packaged such a version for Wheezy yet (it's in Jessie and Sid, though), and I really only need the certificates (the security fixes listed on the front page don't apply in my situation).
I tried going into Tools -> Certificates and delete all SSL certificates that had
msn in their host names, and when I reconnect after that it installs certificates for
login.live.com, but I am still getting the exact same error.
While waiting and hoping for Debian to package an upgrade, is it possible to use the certificates packaged with Pidgin 2.10.7 (either the official source code or the Debian package from Jessie or Sid) with the 2.10.6-3 build as distributed in Wheezy? If so, how? It is OK if this might break on a reinstall of the Wheezy build of Pidgin, because by the time that comes up hopefully the version that would be installed is fixed anyway.
Edit I downloaded and installed Pidgin 2.10.7-2 (specifically the pidgin, pidgin-data, libpurple0 and libpurple-bin packages) from Jessie, confirmed that I am running those (through dpkg and Pidgin's About dialog), deleted the Live and MSN certificates and reconnected, but I am still getting the same error.
