**Miz** · 01-10-2007, 09:15 AM

Version 4.0.5_GA_518.RHEL4 Dec 18, 2006

- All Zimbra services running (minus Perdition, not used)
- All webservices working properly
- HTTPS mode
- Custom port
- SASL URL is correct (zimbra_url)
- zimbraMtaAuthURL is correct

- libexec/zmfixperms has been run successfully
- all services have been recently restarted

/var/log/zimbra.log:

Code:

Jan 10 11:59:39 nobox postfix/smtpd[12391]: warning: SASL authentication failure: cannot connect to saslauthd server: Permission denied

Help?

add this line to /etc/syslog.conf and then restart (kill -1) syslogd:
auth.* -/var/log/zimbra.log

that will send the saslauthd logging there instead of nowhere. go ahead and post the output of these commands as well:

su - zimbra
zmprov getServer nobox.whatever.com | grep -e Mode -e Auth -e Port
cat ~/cyrus-sasl/etc/saslauthd.conf*

I verified that syslogd restarted as a result of the kill command, after editing the syslog.conf, and made the change before attempting to log in via SMTP/TLS again.

/opt/zimbra/conf/smtpd.crt is:

Code:

-rwx------  1 zimbra zimbra 1078 Jan 18 10:24 /opt/zimbra/conf/smtpd.crt

And appears to be a well-formed certificate.

/opt/zimbra/cyrus-sasl/lib/sasl2 is:

Code:

#
# This is ${cyrus-sasl-prefix}/lib/sasl2/smtpd.conf
#
log_level: 3
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
saslauthd_path: /opt/zimbra/cyrus-sasl/state/mux

I uncommented the saslauthd_path and restarted Zimbra's saslauthd using zmsaslauthdctl restart

This resulted in saslauthd finally logging, but these are the only lines it spit out:

Code:

Jan 18 16:20:11 mail saslauthd[9609]: detach_tty      : master pid is: 9609
Jan 18 16:20:11 mail saslauthd[9609]: ipc_init        : listening on socket: /opt/zimbra/cyrus-sasl-2.1.21.ZIMBRA/state/mux

On my system, I see:

Code:

$ ls -al /opt/zimbra/cyrus-sasl/state/

What do you have?

**anand** · 01-18-2007, 02:08 PM

How about:

Code:

# ldd /opt/zimbra/postfix/libexec/smtpd  | grep sasl
        libsasl2.so.2 => /opt/zimbra/cyrus-sasl/lib/libsasl2.so.2 (0x0000002a95a00000)

Path to the socket is hard coded in SASL client libs (I think), and this will tell us if you are using the lib that came with Zimbra or not.

Infact the sure fire way to check this is to find a live "smtpd" process and pmap it.

Code:

 # pmap 12314 | grep sasl2.so
0000002a95a00000     88K r-x--  /opt/zimbra/cyrus-sasl-2.1.21.ZIMBRA/lib/libsasl2.so.2.0.21
0000002a95a16000   1024K -----  /opt/zimbra/cyrus-sasl-2.1.21.ZIMBRA/lib/libsasl2.so.2.0.21
0000002a95b16000      4K rw---  /opt/zimbra/cyrus-sasl-2.1.21.ZIMBRA/lib/libsasl2.so.2.0.21

**Miz** · 01-18-2007, 02:15 PM

Code:

# ldd /opt/zimbra/postfix/libexec/smtpd | grep sasl
        libsasl2.so.2 => /opt/zimbra/cyrus-sasl/lib/libsasl2.so.2 (0xb7d65000)

Now there's an interesting find...

No smptd.

I had one a minute ago.
