Hi list, I retried everything and probably found some new insights: Am Sonntag, 14.

I thought this was due to self-signed certificates but it doesn't seem to be. The client gives me a "no worthy mechs" after negotiating TLS. As I have my users on an ldap server I'm using saslauthd and advertise PLAIN. I tried 'imtest -t "" -m PLAIN -a manager master' and it works as well. Is PLAIN disallowed for frontend-backend authentication? Is there a way to get more debug-output?
