postfix sasl "cannot connect to saslauthd server: No such file or directory"
I try to setup postfix with smtp authentication. I want to use /etc/shadow as my realm
Unfortunately I get a "generic error" when i try to authenticate
# nc localhost 25
220 mail.foo ESMTP Postfix
AUTH PLAIN _base_64_encoded_user_name_and_password_
535 5.7.8 Error: authentication failed: generic failure
In the mail.warn
logfile i get the following entry
Oct 8 10:43:40 mail postfix/smtpd[1060]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
Oct 8 10:43:40 mail postfix/smtpd[1060]: warning: SASL authentication failure: Password verification failed
Oct 8 10:43:40 mail postfix/smtpd[1060]: warning: _ip_: SASL PLAIN authentication failed: generic failure
However the sasl setup seems to be fine
$ testsaslauthd -u _user_ -p _pass_
0: OK "Success."
i added smtpd_sasl_auth_enable = yes
to the main.cf
This is my smtpd.conf
$ cat /etc/postfix/sasl/smtpd.conf
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
saslauthd_path: /var/run/saslauthd/mux
autotransition:true
I tried this conf with the last two commands and without.
I'm running debian stable.
How can postfix find and connect to the saslauthd server?
Edit:
I'm not sure whether postfix runs in a chroot The master.cf looks like this: http://pastebin.com/Fz38TcUP
saslauth is located in the sbin
$ which saslauthd
/usr/sbin/saslauthd
The EHLO has this response
EHLO _server_name_

Are you perhaps missing the symlink from /var/run/saslauthd to /var/spool/postfix/var/run/saslauthd?
From my working system:
root@mail:/etc/postfix/sasl# ls -la /var/run/saslauthd
lrwxrwxrwx 1 root root 36 Dec 31 2010 /var/run/saslauthd -> /var/spool/postfix/var/run/saslauthd
