Hello all,
I'm working with director in tandem with 'director_tags' to group some backend hosts. I've assigned the groups to the hosts by appending a '@' character after the IP address of a backend host under director_mail_servers:
...
director_mail_servers = 192.168.0.1@foo 192.168.0.2@bar 192.168.0.3@foobar
...
I can confirm that the backend hosts possess the correct tags by issuing:
# doveadm director status mail server ip tag vhosts state state changed users 192.168.0.1 foo 100 up - 0 192.168.0.2 bar 100 up - 0 192.168.0.3 foobar 100 up - 0
And examining that the tags have been assigned correctly.
My passdb lookup is using mysql, and it appears as such:
passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql }
This file looks like:
driver = mysql
connect = host=localhost dbname=xxx user=xxx password=xxx
password_query = select director_tag, username, domain, password, 'Y' as
proxy from users where username = '%n' and domain = '%d'
iterate_query = select director_tag, username, domain from users
I have a database that contains the following columns:
username, domain, password, home, UID, GID, active, and director_tag
To assign users to a backend, I went off of the documentation that states:
" A passdb lookup can return "director_tag" field containing the wanted tag name. "
To fulfill this, I return the 'director_tag' in the passdb lookup, through password_query.
The mapping seems to work. When I change the row in the database, the user gets proxied to the new backend on the next connection.
However, My question is, Why does this appear in the logs?
"dovecot[1963]: imap-login: Debug: Ignoring unknown passdb extra field: director_tag"
How could this be an unknown passdb extra field, when the documentation states that you may return a field containing this key?
In the file core/src/login-common/client-common-auth.c - Starting at line 142, there is no if condition checking for 'director_tag'. This causes that line to be output to debug handle.
Is this intentional?
Thank you for your time.
