No MSN with Adium, Pidgin or other libpurple-based IM client? Here’s why..

UPDATE: For those using Pidgin, you can install msn-pecan. It works and it brings some new functionality. Just install it and change your account protocol from MSN to WLM.

I’ll be quoting the Adium blog which apparently is now down (all adiumx.com domain is unreachable actually).

Starting at about 20:00 PST tonight (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.

In case you’re wondering, this also affects Pidgin, which means it’s definitely not an Adium problem.

There are two ways to connect:

We’re not sure 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. If it turns out to be the latter, we’ll almost certainly include that Libpurple update in our next 1.3.3 beta.
