[Pkg-exim4-users] cram_md5 authentication between exim3 and exim4

[Norbert Preining]

Hi all!

I have a question concerning exim and cram-md5 authentication:

We have a server running exim3 (debian woody) and the following entry in
the config file
# AUTHENTICATION CONFIGURATION
cram:
  driver = cram_md5
  public_name = CRAM-MD5
  server_secret = ${lookup{*}lsearch{/etc/exim/clientpasswd}{$1}fail}
  server_set_id = $1

and the corresponding /etc/exim/clientpasswd file:
gandalf:foobar

the client uses exim4 (debian sid) and the following config file
snippet:
begin authenticators
cram_md5:
  driver = cram_md5
  public_name = CRAM-MD5
  client_name = ${extract{1}{:}{${lookup{$host}lsearch*{CONFDIR/passwd.client}{$value}fail}}}
  client_secret = ${extract{2}{:}{${lookup{$host}lsearch*{CONFDIR/passwd.client}{$value}fail}}}

with the following entry in /etc/exim4/passwd.client:
our.mail.server.com:gandalf:foobar

I have our.mail.server.com as smart host, but when I try to deliver an
email via this server the following happens (log from server exim):
SMTP<< EHLO gandalf.localdomain
set_process_info:  8606 handling incoming connection from host28-221.pool80183.interbusiness.it (gandalf.localdomain)

250-SIZE

250 HELP
SMTP<< AUTH CRAM-MD5
SMTP>> 334 PDg2MDYuMTEyMTE4NTczMkBhbHBoYS5sb2dpYy50dXdpZW4uYWMuYXQ+
SMTP>> 535 Incorrect authentication data
LOG: 0 MAIN REJECT

So there seems to be an error in my configuration, but I cannot see
where it is. Can someone help me getting this fixed?

Best wishes and thanks a lot

Norbert

DUNBAR (n.)
A highly specialised fiscal term used solely by turnstile
operatives at Regnet's Part zoo. It refers to the variable amount of
increase in the variable gate takings on a Sunday afternoon, caused by
persons going to the zoo because they are in love and believe that the
feeling of romance will be somehow enhanced by the smell of panther
sweat and rank incontinence in the reptile house.
