Well... there is that usetdb passwd which seems bit extraneous.

I'd remove the

userdb {
driver = passwd
}

section

Thanks Aki - the trick was finding where that setting was! Found
it in auth-system.conf.ext.

Commented it out and all works perfectly now.

Thanks again Aki,

James.

I'll throw in my 2 cents that it'd be great for a passdb/userdb block to have a setting to suppress that message. I've actually changed my mind and *not* used extra userdbs in the past (despite there being good reasons to use them) entirely due to that log entry. We've got millions of mailboxes and the noise in the logs would be unreal. And it would cause no end of confusion for ops people looking at logs. I weighed the likelihood that I'd end up being asked a million times why a login failed, when in reality it hadn't, and decided it wasn't worth the headache.

Or alternatively only log that error when *all* of the passdbs/userdbs have failed. Anything would be better than logging what *looks* like an error but isn't. And, yes, i see 'info' in the log entry, but 'unknown user' is far more eye-catching.

This is the part where someone points out that there already *is* a setting for this and I stop talking :)

auth_verbose=no
