Hi,
The documentation at https://wiki.dovecot.org/UserDatabase/ExtraFields
states that "It's possible to override settings from dovecot.conf", as
well as the following:
> If you want to override settings inside sections, you can separate
the > section name and key with '/'. For example:
>
> namespace default {
> inbox = yes
> separator = .
> location = maildir:~/Maildir
> }
>
> The separator setting can be overridden by returning
namespace/default/separator=. extra field.
As such, we would expect for it to be possible to override
mail_max_userip_connections under the "protocol imap" section, with a
passwdfile userdb looking something like this:
example:{CRYPT}x:1011:1011::/mail/example::userdb_protocol/imap/mail_max_userip_connections=100
The userdb returns the expected fields in the correct format (according
to the documentation):
# doveadm user -u example
userdb: example
user : example
uid : 1011
gid : 1011
home : /mail/example
protocol/imap/mail_max_userip_connections: 100
However, this new setting is not honoured. To test, I set
"mail_max_userip_connections=1" in 20-imap.conf, and noticed that my
second connection was closed with the following error:
dovecot[13573]: imap-login: Maximum number of connections from
user+IP exceeded (mail_max_userip_connections=1)
I also attempted the same setting, without the "protocol/imap" prefix.
Is this not possible? Are there restrictions to what settings may be
overridden in userdb? The documentation appears to suggest that there isn't.
Best regards,
Eirik Rye
