Dovecot and Oauth

[Michael Hallager]

Hi all,

I am considering expanding a mail server to support Oauth with Google. I 
have read through the following:
https://wiki.dovecot.org/PasswordDatabase/oauth2
however, it doesn't work and appears to me to be missing important 
information, the least of which is API authorisation. Searching with 
Google, I can't find any more information beyond what amounts to C&P'ing 
of the above link.

Has anyone successfully deployed Oauth with Google and could they please 
send me their config files?

Thanks,

Michael
