Me neither ;-)

I believe EXTERNAL should allow for SSL/TLS authentication (for example if
client has certificate and is listed in access.db).  But I'm not sure.  
I don't
use it, I left it since it was there by default (only removed GSSAPI 
and two MD5
mechs since those are useless for me in this installation).

Anyhow, removing EXTERNAL does not make any difference.  I'll leave it out of
the configuration for now, just to rule out posiblity that it has any 
influence
on the problem I have.

Yes, saslauthd is running and correctly configured.  I've tested it with
testsaslauthd, and it works.
