Unknown setting error with dovecot-sql.conf.ext

Hi All,

I am trying to install Dovecot connecting to MySQL and all seems to be working until I try to send/receive.

I'm getting a "Unknown setting" error for anything that is inside dovecot-sql.conf.ext

dovecot-sql.conf.ext is inside /etc/dovecot and is referenced from /etc/dovecot/conf.d/auth-sql.conf.ext

The error I get is:

auth: Fatal: sql /etc/dovecot/dovecot-sql.conf.ext: Error in configuration file /etc/dovecot/dovecot-sql.conf.ext line 1: Unknown setting: driver

Can anybody help me?

Andy
