[introduction: new to the list, used dovecot w/exim as MTA in simple ways for 2 years, blah blah blah]

i'm trying to get exim to use dovecot auth with a copy of rc27 and am missing something that's probably quite simple.

specifically, how does one configure the authenticators in dovecot.conf for rc27? the auth section of the default config file installed in rc27 doesn't entirely look like what i'm seeing in other documentation; instead of

auth default {

}

i'm seeing

auth = default

followed by lots of standard flags prefixed by auth_, but i don't see how to set up the socket. i have the following; dovecot starts and doesn't complain but it doesn't create the socket either:

auth_socket listen { client { path = /var/run/dovecot/auth-client mode = 0660 user = exim group = exim } }

any suggestions?

thanks, richard
