Other possibilities are:"
/etc/groups won't be queried now, because of the different driver.

"passwd-file" is similiar to "passwd", but I don't know, if you break
something (outside Dovecot), if you add the last field to /etc/passwd.
Because Dovecot supports multiple userdb's, you could add a passwd-file
userdb _before_ passwd userdb, copy the line of sarah from /etc/passwd
into that new file and add the extra fields there. See
http://wiki2.dovecot.org/AuthDatabase/PasswdFile
userdb {
driver = passwd-file
args = username_format=%n /etc/dovecot/imap.passwd
}
userdb {
driver = passwd
}
This works. But I noticed when I do use it to override mail_location
dovecot doesn't report system_groups_user anymore. Not sure if that
matters
$: dovecot user sarah
field value
uid 1403
gid 101
home/home/sarah
mailmbox:~/mail:INBOX=/var/mail/sarah
system_groups_user sarah
Now I add to imap.passwd:
sarah::1403:101::/home/sarah::userdb_mail=maildir:~/Maildir
$: dovecot user sarah
field value
uid 1403
gid 101
home/home/sarah
mailmaildir:~/Maildir

You can do so. Dovecot really does not care where the user data comes
from.
But, I wonder why you would need the extra DB with mySQL.
a) You can add new fields to the DB on the fly at runtime and adjust
the query in Dovecot and reload.
b) http://wiki2.dovecot.org/UserDatabase/ExtraFields; make use of
"userdb_import" - generic field with delimited settings.

Close, but not the same. Look back at Steffen's post. There are TWO
userdb definitions. Do it that way and all is well. He answered you
completely.

Only one user had a userdb entry. If you specify a userdb, the
built-in defaults do not apply.

This looks very interesting to me...
I've been contemplating slowly converting users (one at a time) over to
SIS storage - looks like this would work for doing that too?
The main thing holding me back is/was the MySQL DB I use for userdb
doesn't natively/easily support extra fields - so, with this method, I
could add a passwd-file userdb with the extra field(s) *before* my
passwd userdb, then add the users to convert one by one, then once all
are converted, change the main config and eliminate the temporary
userdb... ?
Thanks!

Re: [Dovecot] Change mail_location for one user?
I tried something similar already.
passdb {
driver = shadow
}
userdb {
driver = passwd-file
args = username_format=%n /path/to/passwd
}
With only the one sarah user defined in /path/to/passwd. But then all
other users cannot log in anymore. Thunderbird says "Sending of
password did not succeed". Does anyone know if specifying a userdb
stops passdb/shadow from being used? Do I need to copy all users from
the passdb/shadow system to /path/to/passwd? Was hoping to just specify
single users I wanted to override in /path/to/passwd.

[Dovecot] Change mail_location for one user?
Hello, I'm running the latest version of dovecot on Linux with mbox
mailboxes. Everything works fine. So in my dovecot config I have
mail_location = mbox:~/mail:INBOX=/var/mail/%u
I would like to now change the mail_location for one user in an attempt
to slowly migrate to Maildir format. I'm confused how to do this. I'm
running shadow passwords:
$: doveconf -n passdb
passdb {
driver = shadow
}
Testing any given user gives:
$: dovecot user sarah
field value
uid 1478
gid 116
home/home/sarah
mailmbox:~/mail:INBOX=/var/mail/sarah
system_groups_user sarah
What would I have to do to make only sarah's mail_location ~/Maildir
now? My userdb is:
$: doveconf -n userdb
userdb {
driver = passwd
}
I tried following the wiki's but its confusing. Thanks for any help or
tips.
