dovecot - May 2012 - Exim / Dovecot and AUTH LOGIN

Hi to both adressed mailing lists,

I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL

exim.conf:

|   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


10-master.conf for dovecot:

|   service auth {
|     # auth_socket_path points to this userdb socket by default. It's
typically
|     # used by dovecot-lda, doveadm, possibly imap process, etc. Its default
|     # permissions make it readable only by root, but you may need to relax
these
|     # permissions. Users that have access to this socket are able to get a
list
|     # of all usernames and get results of everyone's userdb lookups.
|     # unix_listener auth-userdb {
|       #mode = 0600
|       #user |       #group |     # }
|   
|     # Exim SMTP AUTH
|     unix_listener auth-client {
|       mode = 0660
|       user = exim
|       group = exim
|     }


PLAIN Authentication works perfect, LOGIN gives 

2012-05-08 15:08:43 login authenticator failed for xxxxxx.tu-berlin.de
[130.149.X.YY]: 435 Unable to authenticate at present: authentication socket
protocol error


Where is the problem? 



Kind regards,
Frank Elsner
