Please read the comments in the headers of configuration files. You  
should *never* modify this file. With each upgrade, these files may be  
overwritten, so it is *mandatory* to put all modifications in  
backends.local.php. Note that these are not example configurations.

Don't. Start with a simple configuration where you authenticate  
against an IMAP server and go on from there.

This has nothing to do with the Horde configuration files, test.php  
doesn't use them. The authentication in Dovecot isn't working somehow.

Why have you configured Dovecot to authenticate against mysql? Do you  
want to use system users, or virtual users here?
