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.

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

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.

adduser postfix sasl

Thanks, this worked for me
