Hi,

this shouldn't be to hard.

Your dovecot-sql.conf.ext could look something like this:

driver = mysql connect = host=<host> dbname=<dbname> user=<username> password=<password>

default_pass_scheme = BLF-CRYPT password_query =
SELECT
u.username,
u.password,
FROM <JOOMLA_PREFIX>_users u
LEFT JOIN <JOOMLA_PREFIX>_user_usergroup_map g ON u.id = g.user_id
WHERE
u.username = '%u' AND u.block = 0 AND g.group_id = <ID OF THE JOOMLA GROUP>

user_query =
SELECT
u.username,
u.password,
FROM <JOOMLA_PREFIX>_users u
LEFT JOIN <JOOMLA_PREFIX>_user_usergroup_map g ON u.id = g.user_id
WHERE
u.username = '%u' AND u.block = 0 AND g.group_id = <ID OF THE JOOMLA GROUP>

iterate_query = SELECT username AS user FROM <JOOMLA_PREFIX>_users u
LEFT JOIN <JOOMLA_PREFIX>_user_usergroup_map g ON u.id = g.user_id
WHERE
u.block = 0 AND g.group_id = <ID OF THE JOOMLA GROUP>

But I'm not sure if dovecot supports Blowfish $2y$ Version used by Joomla as default.

Also I didn't tested this configuration, so there maybe someflaws in it.

Hello,

did anyone ever set up Authentication via lookups to a Joomla (mysql) database?

What I'd like to do is lookup Joomla users (who are in specific/multiple groups) in the Joomla database and then fallback to /etc/passwd authentication to let system users authenticate.

I'm running : # 2.2.35 (b1cb664): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.1-RELEASE-p10 amd64

Thanks in advance,

-Graham-
