Virtual Users And Domains With Postfix... saslauthd restart errors
 
Howto: Virtual Users And Domains With Postfix, Courier, MySQL and SqirrelMail by falko

Problem: Saslauthd does not start, stop or restart and consistently lists these "command not foundthd:" errors. Any clue, or any clue where I could look for clues?


root@harmsen:/etc/postfix# /etc/init.d/saslauthd restart
: command not foundthd: line 5:
: command not foundthd: line 8:
: command not foundthd: line 12:
: command not foundthd: line 16:

, edit /etc/default/saslauthd and set START=yes
root@harmsen:/etc/postfix#

After googling around and translating forum pages it seems I'm not the only one who has had this problem but nobody has posted a solution. I'm totally stuck. I've been tearing my hair out from this for hours and would appreciate help if anyone would be so kind.

Thanks, Leif Harmsen

What's in /etc/init.d/saslauthd and /etc/default/saslauthd?

Code:

#
# Settings for saslauthd daemon
# Please read /usr/share/doc/sasl2-bin/README.Debian for details.
#

# Should saslauthd run automatically on startup? (default: no)
START=yes

# Description of this saslauthd instance. Recommended.
# (suggestion: SASL Authentication Daemon)
DESC="SASL Authentication Daemon"

# Short name of this saslauthd instance. Strongly recommended.
# (suggestion: saslauthd)
NAME="saslauthd"

# Which authentication mechanisms should saslauthd use? (default: pam)
#
# Available options in this Debian package:
# getpwent  -- use the getpwent() library function
# kerberos5 -- use Kerberos 5
# pam      -- use PAM
# rimap    -- use a remote IMAP server
# shadow    -- use the local shadow password file
# sasldb    -- use the local sasldb database file
# ldap      -- use LDAP (configuration is in /etc/saslauthd.conf)
#
# Only one option may be used at a time. See the saslauthd man page
# for more information.
#
# Example: MECHANISMS="pam"
MECHANISMS="pam"

OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"

The first line of /etc/init.d/saslauthd must be
Code:

#!/bin/sh
not
Code:

#! /bin/sh

leif@harmsen.net 1st January 2010 18:11

No difference.
 
Thanks for catching that space, but after removing it and attempting
/etc/init.d/postfix restart
/etc/init.d/saslauthd restart

I still get the exact same problem / error response.

Postfix and Mysql are working fine, incoming messages are piling up as they should under home/vmail. Just saslauthd remains unhappy.

leif@harmsen.net 1st January 2010 19:21

empty lines appearently causing trouble!
 
I just noticed that the line numbers in each "command not foundthd" error correspond to the lines that are completely blank in /etc/default/saslauthd, so the errors must be referring to that file. I'm not sure why blank lines would cause errors!? I'm investigating now.

leif@harmsen.net 1st January 2010 19:57

Fixed with dos2unix!
 
I must have edited or perhaps only looked at /etc/default/saslauthd while at my boyfriend's flat - he runs Microsoft Windows which apparently writes all kinds of invisible crap like redundant line-feed rubbish in text files that remain invisible even with nano or vi on Linux! The blank lines causing errors was the clue that led me to learn about the "dos2unix" utility that fixed the file. Thank you Falco for pointing me to the suspect file.

Code:

root@harmsen:/# dos2unix /etc/default/saslauthd
root@harmsen:/# /etc/init.d/saslauthd stop
 * Stopping SASL Authentication Daemon saslauthd                        [ OK ]
root@harmsen:/# /etc/init.d/saslauthd start
 * Starting SASL Authentication Daemon saslauthd                        [ OK ]
root@harmsen:/#
