Adium is a free instant messaging application for Mac OS X that can connect to AIM, MSN, Jabber, Yahoo, and more
Starting at about 20:00 PST (January 11), Microsoft’s servers have stopped accepting logins from clients that use version 15 of the protocol, including Adium 1.3.2. The Debug Window in debug and beta versions of Adium reveals that their server is failing to find a certificate that it needs when Libpurple attempts to retrieve your MSN Address Book.
This also affects Pidgin, which means it’s definitely not an Adium problem.
There are two ways to connect:
- Use Microsoft Messenger for Mac, the official client.
- Use Adium 1.3.1, the previous version of Adium.
It is not clear whether this is a temporary server problem or a permanent change that will break P15-using Libpurple-based clients (including Adium 1.3.2) until a future Libpurple release.
