How do I use Freenode IRC with SASL in Adium? I received the following error when trying to join Freenode with Adium:

*** Notice -- You need to identify via SASL to use this server

I understand why they want me to use SASL in my case, and I can see this is a common problem. I can see that Adium supports SASL, and I can find the help ticket that prompted the Adium dev group to add SASL support.

What I can't find is... how to use SASL in Adium. I don't see any options for enabling SASL or configuring it or anything. Thanks for your help.
Adium 1.5 doesn't support using SASL for IRC. That will be added in 1.6: https://trac.adium.im/ticket/14478.

In 1.6, there will be a checkbox to activate SASL. When that is activated, the password field is treated as the SASL password.

The following build can be used successfully: Adium_1.6hgr5915.dmg

And this guide may help if you have question using it after you've enabled SASL.
