saslauthd

About

saslauthd is a SASL authentication daemon. It works with Dovecot and Postfix but is (as far as I can tell) provided separately.

Configuration is in /etc/default/saslauthd.

Testing

testsaslauthd -u username -p password

This should be a system username, rather than a dovecot virtual username, if Dovecot is configured for virtual users.

Notes

Despite the existence of /var/spool/postfix/var/run/saslauthd if Postfix is installed, and a comment in the config file suggesting that OPTIONS can be set to use it, it actually is not happy with this, and will return this message:

connect() : No such file or directory

...if the Postfix version is used, instead of...

0: OK "Success."

...if the regular /var/run/saslauthd file is used.
