postfix auth problem (sasl)

[lerra]

Hi! I cant use my postfix to send mail, i get this when i try to send it in the logs:

Mar 6 08:44:01 caveguard postfix/smtpd[4915]: setting up TLS connection from xxxx[xxx]
Mar 6 08:44:01 caveguard postfix/smtpd[4915]: TLS connection established from xxxx[xxx]: TLSv1 with ciith cipher RC4-MD5 (128/128 bits)
Mar 6 08:44:01 caveguard postfix/smtpd[4915]: connect from xxxx[xxx]
Mar 6 08:44:01 caveguard postfix/smtpd[4915]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
Mar 6 08:44:01 caveguard postfix/smtpd[4915]: warning: xxxx[xxx]: SASL LOGIN authentication failed
Mar 6 08:44:01 caveguard postfix/smtpd[4915]: warning: Read failed in network_biopair_interop with errno=0: num_read=0, want_read=5

Mar 6 08:44:06 caveguard postfix/smtpd[4915]: setting up TLS connection from xxxx[xxx]


Anybody that knows what to do? What coud be the problem? I see that the TLS phase works, but when it try to identify the user it cant find db

Here is some other configs:
caveguard:~# cat /etc/default/saslauthd
# This needs to be uncommented before saslauthd will be run automatically
START=yes

PARAMS="-m /var/spool/postfix/var/run/saslauthd"

# You must specify the authentication mechanisms you wish to use.
# This defaults to "pam" for PAM support, but may also include
# "shadow" or "sasldb", like this:
# MECHANISMS="pam shadow"

MECHANISMS="pam"
#PARAMS="-m /var/spool/postfix/var/run/saslauthd -r"

and fro my main.cnf:
smtpd_sasl_local_domain =
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination

And
caveguard:~# cat /etc/postfix/sasl/smtpd.conf
pwcheck_method: saslauthd
mech_list: plain login
allow_plaintext: true

Any tip?

[falko]

saslauthd isn't running. Start it: /etc/init.d/saslauthd start

[lerra]

<quote>
caveguard:~# /etc/init.d/saslauthd start
Starting SASL Authentication Daemon: /usr/sbin/saslauthd already running.
</quote>

[falko]

Then try /etc/init.d/saslauthd restart

[lerra]

Still the same error:)

[falko]

Which distribution do you use?

[lerra]

Debian sarge 3.1 amd64. Followd your howto in perfect setup for debian 3.1

[falko]

Please redo the saslauthd configuration from http://www.howtoforge.com/perfect_setup_debian_sarge_p4 . Maybe you made a typo somewhere.

[lerra]

Still the same error:(

[falko]

Please post the output of ps aux|grep sasl

What do you have in your thoughts?

[todvard]

My first thoghts was that you are using postfix not in chroot and you are trying to access saslauthd in wrong folder, but everything seems fine in your config files and folders so far.
I could find some hints searching by google, this one is promising http://bsdsearch.com/eao/phorum/read.php?f=38&i=2810&t=2810&v=f
Lets see other config files
cat /etc/init.d/saslauthd

/* about your main.cf, i guess you forgot to install procmail, or just forgot to configure postfix to using it.
mailbox_command = procmail -a "$EXTENSION"
just ignore me if you are planning to not use procmail :) */

[lerra]

What feutures will procmail do? Or what does it add?

[falko]

Looks ok, too... :confused:

[todvard]

What feutures will procmail do? Or what does it add?

Procmail is needed for selecting and forwarding messages to different services like the spamfilter, virusscanner, mail forward, quota, autoresponder and such..
I hope Falko or Till will correct me if i am wrong.. :)

about sasl, i can not see errors im your config files. it could be smthing very annoying typo somewhere.. or maybe not.. :confused: If i were you i would reinstall all packages related to this issue:
apt-get --reinstall install postfix postfix-tls libsasl2 libsasl2-modules sasl2-bin

[lerra]

Hm, i already use thows feutures and they seams to work..
Hm, ok, i will do that and come back...will follow perfect setup 3.1 debian again and report back.

[lerra]

Is there nobody that can help me with the sasl problem? Still haveing the problem.. :/

[falko]

You must have something wrong. If you simply copy & paste the commands from the "Perfect Setup", it will work.

[r12dk]

Falko, i think something has changed in the debian packages since you wrote the howto. Lot of people seem to have problems with saslauth and smtp auth'ing, including me.

I also followed the perfect setup, step by step, and it simply wornt work.

[falko]

Believe me, it's working. I've just set up another server with this tutorial two days ago. If you just follow it and don't look left and right, then it's working. Don't do anything else, just do what is said in the tutorial.

[lerra]

Solved! After some hours of googleing and testing i found a page:
http://lists.debian.org/debian-user/2005/07/msg01010.html

What i did was that i added postfix to the sals group,
rm -rf /var/run/saslauthd
ln -s /var/spool/postfix/var/run/saslauthd/ /var/run/saslauthd

And it works now! I am runnign Sarge 3.1 amd64
I hope this will help people, please support the ispconfig community by postback sollutions! Creds to the codehackers!

I have the same problem,and dont work with that commands. I do a vimdiff from my files to howto's configuration files and are the same except the domain, of course.

update:
Im restart all services and now (thanks to $deity) gives an error:
warning: SASL authentication failure: cannot connect to saslauthd server: Permission denied

And with testsaslauthd runs well, before the restart dont work:
testsaslauthd -f /var/spool/postfix/var/run/saslauthd/mux -u minskog.net_minskog -p password
0: OK "Success."

Update 2:
lerra have: PWDIR="/var/spool/postfix/var/run/${NAME}"
I have: PWDIR=/var/run/saslauthd


But ig i put PWDIR="/var/spool/postfix/var/run/${NAME}", then sasl dont start.

[falko]

Please kill your existing saslauthd processes and try to start saslauthd again.

[minskog]

I restart it a lot, but i think that the problem could be here:

Starting SASL Authentication Daemon: mode of `/var/run/saslauthd' changed to 0710 (rwx--x---)

Update:

If i put /var/spool/postfix/var/run/saslauthd with 777, dont gives permission error, but continues giving errors, the password is correct and the user, I use them with imap, pop and testsasauthd, and works perfectly:

warning: SASL authentication failure: Password verification failed

[falko]

Did you kill your existing saslauthd processes and start saslauthd again?

[minskog]

Did you kill your existing saslauthd processes and start saslauthd again? Yes, and the same: server1:/var/spool/postfix/var/run/saslauthd# killall saslauthd
