Adium users are experiencing login problems today when they try to access MSN. Adium is a very popular MacOS IM client. It appears that MSN is rejecting connections from Adium 1.3.2. In fact, Pidgin users are also affected. Below info is taken from Adium’s blog. (The site is loading very slowly tonight. Most likely because everyone is accessing Adium’s website to check out what went wrong.)

MSN rejecting Adium 1.3.2 connections

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:

Use Microsoft Messenger for Mac, the official client.
Use Adium 1.3.1, the previous version of Adium.
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.

I’m currently using Microsoft Messenger for Mac which reminds me why I switched to Adium in the first place. Let’s hope that this problem can be resolved quickly or I’ll downgrade to Adium 1.3.1.

Update: The problem has been resolved. Adium 1.3.2 is able to connect to MSN now.
