[Dovecot] auth: Fatal: Unknown passdb driver 'mysql'

[Vaidas Jablonskis]

Hi People,

I am setting up a new dovecot server for testing first prior production
upgrade from 1.2.x to 2.0.x.

I used the RPMs from ATrpms: dovecot-2.0.0-1_117.el5.x86_64.rpm

The errors I am getting:

-----------------------------

It is clearly seen that mysql drivers are installed and being loaded during
dovecot startup.

-----------------------
/etc/dovecot/conf.d/auth-sql.conf.ext

passdb {
  driver = mysql
  args = /etc/dovecot/dovecot-sql.conf.ext
}

userdb {
  driver = prefetch
}

userdb {
  driver = mysql
  args = /etc/dovecot/dovecot-sql.conf.ext
}
-------------------------

Any ideas what else could be wrong?

Thanks,
Vaidas
