Hello Traiano,

I think <AuthBy SQL> is what you should consider. Try something like this:

<AuthBy SQL>
    DBSource        dbi:...primaryDb
    DBUsername      username_for_primary_DB
    DBAuth          password_for_primary_DB

    DBSource        dbi:...secondaryDb
    DBUsername      username_for_secondary_DB
    DBAuth          password_for_secondary_DB

    # Rest of settings
</AuthBy>

In other words, define DBSource, DBUsername and DBAuth twice if you have
two databases. That will enable fail over functionality.

For more, please see the reference manual for version 4.9, section "5.31
<AuthBy SQL>". There is one paragraph discussing how the failover with
multiple databases works.

Thanks!
Heikki
