> Can Postfix access the saslauthd socket directory?
> What command line options do you give to run saslauthd?
I'm not sure where the saslauthd socket is. Everyone has read access
to /etc/sasl2/saslauthd and /etc/sasl2/sasldb2, which might be what
you're referring to.

sasl is run as "-a rimap -r -O localhost"

Here's output from a newly-patched version of saslfinger:

-- mechanisms on localhost --

I think there's no mechanisms listed because I have postfix set to
only use TLS.
