I've been trying to crack this problem for over a month, between the exim & cyrus lists. Sometimes I think its a exim issue, sometimes cyrus. I'm back onto cyrus :)
I've posted a lengthy explanation of what I am doing here:
http://groups.yahoo.com/group/exim-users/message/62558
but the short version is:
I have cyrus & exim on the same local server. I am using ldap authentication (saslauths -a ldap), with virtual domains and the ldap authentication is working fine - I can send & receive emails into my ldap users. I am delivering mail from exim to cyus using smtp/lmtp - preauthed using "lmtpd -a" in cyrus.conf
My little problem is that I am trying to use exim's authenticated_sender to bypass the requirement of using anyone post acl's in cyrus so I can post to suffixes. I can't get it to work - because exim doesn't attach the AUTH= param onto the dialog it does with lmtp (verified by debug in exim). It appears that this is because I don't have any auth mechanisms on offer in the lmtp delivery (I am using lmtpd pre-auth "lmtpd -a"), so my questions are:
how do I get lmtp to offer mechs to exim ?
Why doesn't pre-auth work ?
I've always assumed that lmtp would be going via saslauthd, which in turn was authing via ldap - but this migth be wrong ?
I've noticed with pre-auth that ltmp says AUTH EXTERNAL as a mech, but exim just ignores this it seems, and doesn't attach an AUTH= parameter at all onto the MAIL cmd.
I'm not an Exim expert (in fact, I've never used it), but from reading Philip's post, it appears that Exim will not pass AUTH= unless it has authenticated to lmtpd (although RFC 2554 states that this is not required). By pre-authing lmtpd (lmtpd -a), you're preventing Exim from authenticating, unless you can find a way to tell Exim that it can use the EXTERNAL mechanism. My guess is that if you remove the -a option (and connect via TCP) that Exim will do what you want.
