director & backend on same server with director_proxy_maybe

21 May 2021


      Hello,
I've 2 mail servers, as test server, with dovecot as backend and setup
pop3 and imap connections and NFS. For prevent issues with simultaneous
connections I want to setup up Director on the same VM and on the same
instance as the backend Dovecot.
I found in the documentation that this configuration is broken, but can
work with development, and after research on the internet and on the
questions encountered previously as on :
https://dovecot.org/pipermail/dovecot/2015-July/101483.html
https://dovecot.org/pipermail/dovecot/2011-September/130939.html
https://dovecot.org/pipermail/dovecot/2012-June/136535.html
I find it quite unclear if this is really possible with
director_proxy_maybe, which according to the changelog, allows this
setup to work.
Today I've reached this level with those errors:

sql query :
password_query = SELECT password, 'y' as proxy_maybe, 'y' as
director_proxy_maybe FROM mail_user WHERE (login = '%u' OR email = '%u')
AND disable%Ls = 'n' AND server_id = '8'
It seems that Director is working but not adding the "host" extra field
when it should, also it's strange that the director_proxy_maybe is unknown.
Is it really possible to configure director on same instance as backend?
Is director_proxy_maybe working? Also do you have answers about my problems?
Thanks for advance.
