Digging further:
I did some rc.d/init.d tweaking so that I could run either Dovecot version on demand and changed the configuration so that authentication for both is basically the same. 1.07 works and 1.2.17 still doesn't.
I'd really like to understand what's going on here as opposed to just dropping back and declaring it "fixed".
Here is the -n output for both versions, login/mail executables and plugins are present within the configured paths for both versions:

Many thanks,
