Hi,
i'm trying to configure Dovecot proxy with user authentication on
proxy side only, so backends will authenticate using master password
(proxy is configured to send it). The problem is that Dovecot, on
backends, is telling me that i need to configure at least one auth
mechanism:
auth: Fatal: No passdbs specified in configuration file. LOGIN
mechanism needs one
The master auth is correctly configured.
I want to accomplished to have user database only on one place
(=proxy). Any hints?

Can you show your backend doveconf -n?

Try adding another entry after the first passdb (order matters)
passdb { driver = static args = nopassword deny = yes skip = authenticated }

This seems to be working, thank you. Can you explain me why it's needed?

No need to explain it anymore, i understand it now. I made a little
change and (probably) final version is this:
passdb { driver = static args = nopassword skip = authenticated }
I removed 'deny = yes' as, i believe, it's not needed and it was doing
problems with LMTP proxing ('User doesn't exist' error message from
backend LMTP). Thanks again.

Hi!
This is very dangerous configuration, please consider using what Sami suggested, viz
passdb { driver = static args = password=masterpassword }
and remove the master auth completely.
then you can override user's password to masterpassword in proxy config.

This is awesome, as I was just contemplating how to maintain
persistence with 2FA.
Is it possible to use a passdb based on remote ip? There's a
username_filter, but I want to use a master password for webmail
(which will use 2FA via Radius), and those IPs are known and
non-routable.

Maybe just in the SQL passdb would be better...
password_query = SELECT userid as user, if(host =
'192.168.1.1',encrypt('masterpassword'), pass_field) as password,
FROM users WHERE userid = '%u'

passdb { driver = static args = password=masterpassword allow_nets=192.168.0.0/24 }
or can even use single ip like allow_nets=192.168.1.234

Thanks guys, i reworked it like this (i already allowed only proxy IP
on firewall but thanks for suggestion, i added also allow_nets, just
to be sure) and everything is working fine.

In the config sample provided in another mail you have configured master *user* passdb but in this mail you talk about master password passdb? which one it is?
I think for what you are trying to achieve, master password auth is more suitable. So change your passdb to something like this:
passdb { driver = static args = password=masterpassword }
simple as that.
