This authentication plugin uses Dovecot's SASL mechanism to validate user's credentials. By default it tries to connect to /var/run/dovecot/auth-client socket and sub- mits authentication challenge using Dovecot's protocol. Only PLAIN mechanism works so far, should not be a prob- lem over encrypted TLS channel which is already de-facto standard in modern communications. Example configuration section: Realm djabberd Socket /var/lib/djabber/dovecot-sasl Note: Dovecot by default sets restrictive permissions on the socket so if you need to run djabberd as an unprivi- leged user (good idea after all) you need to configure the socket in dovecot and Authen section.
