[Dovecot] Authentication failed (migrate from 2.0.13 to 2.0.17)

[Dovecot user]

There's no way to troubleshoot this error ? 

I use the same config
file for dovecot 2.0.13, all works.
Perhaps in 2.0.17, something is
missing in my config file, or there's new keyword... ?? 

'dovecot -n'

authentication is a bit annoying to debug though. But I haven't touched
its code for a long time, so it shouldn't have gotten broken.
