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
