[Dovecot] Master Login using MySQL problem - %{login_domain}
Hi Timo,
Been trying to track this problem down further. The problem seems to be related to verifying the master user failing.
My passdb looks like this:
passdb { driver = sql args = /etc/dovecot/dovecot-domain-owner-sql.conf master = yes pass = yes }
dovecot-domain-owner-sql.conf contains:
user_query = SELECT user_name, domain_name FROM users WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1'
password_query = SELECT user_name, domain_name, password FROM users WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1' AND '%d'='%{login_domain}'
In this example - bill@plf.net is an ordinary user. tom@plf.net is a domain owner. Tom wants to read bills email.
The login is: bill@plf.net*tom@plf.net
This results in tom@plf.net being classified as an unknown user.

Note that the query used to determine that tom@plf.net is valid is the password_query and not the user_query resulting in unknown user. I think that's where the problem is.

Show the whole dovecot -n output and the whole logs when master user is logging in? You've cut away some stuff I'd like to see.

Result:

Note - I have two different kinds of masters here. I have a masteradmin who can read anyone's email and I have domain owners who can read anyone's email in the same domain. At least that is what I'm hoping to do.
Does it log "Master user lookup for login" if you patch Dovecot with http://hg.dovecot.org/dovecot-2.0/raw-rev/7428338c8df2 ?

Ran the patch - here's the results for bill@plf.net*tom@plf.net

Again my query is:
user_query = SELECT user_name, domain_name FROM users WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1'
password_query = SELECT user_name, domain_name, password FROM users WHERE user_name = '%n' AND domain_name = '%d' AND owns_domain='1' AND '%d'='%{login_domain}'

Now - on to the really tricky stuff.

you're not selecting the username LOL. The user query, related to how you are storing your mail and where you are storing it, should be:
SELECT CONCAT('/path/to/mail/root/', mailboxes.domain, '/', mailboxes.username, '/' ), AS home, CONCAT('/path/to/mail/root/', mailboxes.domain, '/', mailboxes.username, '/mail' ) AS maildir, CONCAT('/path/to/mail/root/', mailboxes.domain, '/', mailboxes.username, '/sieve' ) AS sieve_dir, CONCAT('*:storage=', mailboxes.quota, 'M') AS quota_rule WHERE user_name=%n AND domain_name=%d AND owns_domain='1'
/path/to/mail/root/example.com/johndoe is johndoe's home directory /path/to/mail/root/example.com/johndoe/mail is johndoe's maildirectory, where the mail directories, for imap, are stored and the inbox is stored (unless you defined inbox in dovecot.conf through a namespace or something) /path/to/mail/root/example.com/johndoe/sieve is where the sieve scripts are stored (if you use pigeonhole)
*Your mysql userquery should ALWAYS define, at least, your home directory and the mail directory, for dovecot.* If you use mbox or dbox, omit the maildir part but you MUST use the home!
The password query should select the password, not the username and domain; correct your thinking of mysql queries! If you have your passwords stored in md5, default_pass_scheme=md5 should be in your mysql config file.
