Hi,
I currently offer standard LOGIN authentication to my SMTP server
using a few standard passwords from /etc/exim/passwd
I use the default code from Debian exim4 config for this:
login_server:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = "${if
crypteq{$auth2}{${extract{1}{:}{${lookup{$auth1}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"
server_set_id = $auth1
.ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}
.endif
Now I want to add support for logging in with the credentials from
dovecot:
login_dovecot_authdaemon:
driver = dovecot
public_name = PLAIN
server_socket = /var/run/dovecot/auth-client
server_set_id = $auth1
.ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}
.endif
When I enable both of them I unfortunately get:
2011-02-23 16:52:09 Exim configuration error:
two server authenticators (login_server and
login_dovecot_authdaemon) have the same public name (LOGIN)
However, for the first time I want to enable *both* sources. The first
one for people who have already configured their client using the
current passwords.
And the second (dovecot) one for when setting up new users.
Is this somehow possible? Either try login_dovecot_authdaemon when
login_server fails or the other way round?
I don't think you can do it in Exim directly (well, you could obviously
try lookups against multiple passwd type files, by extending the server
condition, but that doesn't appear likely to be useful to you).
What you can do, however, is use multiple authentication databases from
Dovecot (see http://wiki.dovecot.org/Authentication/MultipleDatabases),
that way Exim can use just that as its authentication provider.
(I haven't done this with Dovecot's SASL, but I have with Cyrus).

Luke
