Hi, I'm now running authentication using your saslauthd thing. It works,
but if I dont explicitly give an empty realm then auth.log repots garbage
for the realm in the case of auth failures. I guess it needs a default,
and the check in auth_call_saslauthd() is wrong (wasn't NULL to start).

Why? We might want to switch to GSSAPI in order to secure our NFS network;
given that Cyrus can do it, why not use it for Exim too? Then all you need
is one login for all your files and e-mail--remember those days? Only
these days it'd be OK to do this from home over an insecure network :)

Anyway, thanks for helping get LDAP out of my Exim :)
