Yes, I've it running with exim-4.69 and dovecot-1.2.beta1 but dovecot-1.1.11
also works.
"socket protocol error"? Did you set "driver = dovecot"?
The authenticators from my exim configuration file:
| begin authenticators
|
| plain:
| driver = dovecot
| public_name = PLAIN
| server_socket = /var/run/dovecot/auth-client
| server_set_id = $auth1
|
| login:
| driver = dovecot
| public_name = LOGIN
| server_socket = /var/run/dovecot/auth-client
| server_set_id = $auth1
In the dovecot.conf you have to set
# Number of authentication processes to create
count = 1
And my dovecot.conf contains (in the auth section)
| # It's possible to export the authentication interface to other programs:
| socket listen {
| #master {
| # Master socket provides access to userdb information. It's typically
| # used to give Dovecot's local delivery agent access to userdb so it
| # can find mailbox locations.
| #path = /var/run/dovecot/auth-master
| #mode = 0600
| # Default user/group is the one who started dovecot-auth (root)
| #user =
| #group =
| #}
| client {
| # The client socket is generally safe to export to everyone. Typical use
| # is to export it to your SMTP server so it can do SMTP AUTH lookups
| # using it.
| path = /var/run/dovecot/auth-client
| mode = 0666
| }
| }
Hope this helps.
