Hello list, I'm a mutt user and I use cyrus-sasl with mutt for SASL auth. It was working fine until I upgraded to cyrus-sasl-2.1.22 (from 2.1.21). Now I get "SASL authentication failed!" all the time. I ran mutt in debug mode and this is what I got out of it: ---------- cyrus-sasl-2.1.21 ---------- Mutt 1.5.11 started at Thu Sep 7 19:39:13 2006 .

I looked at the source in lib/saslutil.c and I could see a lot of changes but I couldn't really make sense of it. Can you guys see what's wrong? Thanks Sebastian
