Cannot connect to saslauthd server: Permission denied

[migm]

Hi all,

I saw the other thread on this (chmod 777 .... and so on) and that did not work. I am still getting this error. Here's my postfix configuration (main.cfg). Please let me know what other information I can provide: there's obviously a permissions problems here but I thought saslauthd ran as root.

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name.  The Debian default

Thanks for your help. I had already tried this still getting the following

Apr 26 10:55:19 tcc1 postfix/smtpd[21126]: warning: SASL authentication failure: cannot connect to saslauthd server: Permission denied

Well, i got it to work, but I am not confident that my methodology was very secure.

I ran smtpd with strace debugging turned on and saw the reason that things weren't working was that postfix was searching for my saslauthd file in /var/run/saslauthd. The only mention of the /var/run directory i saw was in the saslauthd init.d file, which i changed to reflect the /var/spool/postfix/var/run/saslauthd directory. That didn't work, so I ended up copying and linking all the files necessary from the /spool directory into the /var/run/saslauthd directory. I can't imagine this is terribly secure?

Where is postfix pulling this /var/run directory from, anyway? If i can change that, I'd rather delete what I've done and do it the correct way.

Thanks!

Postfix is running chrooted, so /var/run translates to /var/spool/postfix/var/run.

My postfix was actually not chrooted in the master.cfg

i found a basic solution described here: http://www.ehcp.net/?q=node/149#comment-668

"Cannot connect to saslauthd server: Permission denied" was caused by permission errors for me. Changed /var/run/saslauthd permissions, chmod a+rx and things worked.

Postfix was not chroot'd and there was no group for saslauthd to add Postfix.

Thanks, this worked for me

For those that all of the above doesn't solve the problem... check your password!

If it has a '#' sign all that is after the # gets ignored in "/etc/pam.d
/smtp" and therefore you will have these nice errors in /var/log/auth.log :

pam_mysql - required option "db" is not set
DEBUG: auth_pam: pam_authenticate failed: Error in service module
