auth/flat_file plugin allows you to create a file containing username
and password combinations, and have relaying users authenticate from that
Note that passwords are stored in clear-text, so this may not be a great idea for large scale systems. However the plugin would be a good start for someone looking to implement authentication using some other form of auth.
IMPORANT NOTE - this plugin requires that STARTTLS be used via the tls plugin before it will advertise AUTH capabilities by the EHLO command. This is to improve security out-of-the-box. Localhost and any IP in RFC1918 ranges are automatically exempt from this rule.
Configuration is stored in
config/auth_flat_file.ini and uses the INI
Authentication methods are listed in the
[core] section under
parameter. Lists of authentification methods are comma separated. Currently
supported methods are:
LOGIN methods are not secure. That is why TLS is required before AUTH is
Users are stored in the
[users] user1=password1 firstname.lastname@example.org=password2
