# 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"



# Additional options for this mechanism. (default: none)

# See the saslauthd man page for information about mech-specific options.

MECH_OPTIONS=""



# How many saslauthd processes should we run? (default: 5)

# A value of 0 will fork a new process for each connection.

THREADS=5



# Other options (default: -c -m /var/run/saslauthd)

# Note: You MUST specify the -m option or saslauthd won't run!

#

# WARNING: DO NOT SPECIFY THE -d OPTION.

# The -d option will cause saslauthd to run in the foreground instead of as

# a daemon. This will PREVENT YOUR SYSTEM FROM BOOTING PROPERLY. If you wish

# to run saslauthd in debug mode, please run it by hand to be safe.

#

# See /usr/share/doc/sasl2-bin/README.Debian for Debian-specific information.

# See the saslauthd man page and the output of 'saslauthd -h' for general

# information about these options.

#

# Example for postfix users: "-c -m /var/spool/postfix/var/run/saslauthd"

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