Ah, that wasn't clear to me.

When using saslauthd, there is no need for exim to access "some kind
of secret file", because this is saslauthd's part.
Or did I get that completely wrong?
But what I didn't yet understand is what the differences between the
following two authenticators are:
saslauthd_plain:
driver = plaintext
public_name = PLAIN
server_condition = ${if saslauthd{{$2}{$3}}{True}{False}}
sasl_plain:
driver = cyrus_sasl
public_name = PLAIN
server_realm = server.linau.de
server_set_id = $2
Or in other words: The first authenticator checks the authentication
data by doing a "saslauthd query". And the second one?
My (maybe wrong) imagination has been that the cyrus_sasl driver in
the second authenticator also queries saslauthd.
(I'm not yet familiar with Cyrus IMAPd, but at the moment I think that
Cyrus IMAP authentication works the same way.)
Regards,
Christian
