Further investigation shows that `doveconf` called
`/usr/lib/dovecot/managesieve` which in return calls `doveconf` again,
but with another uid (possible? I'm not sure) and a few extra arguments,
which causes a call to `glob` in
`src/config/config-parser.c:settings_include` to fail with `GLOB_NOMATCH`.
I'd be appreciate if anyone can provide information on suspicious
permission-relating operation that `managesieve` does before calling
`doveconf`.
I just can't find a way to post reply on previous mails, so I decided
to post a new one. The original text follows.

While line 98 of dovecot.conf is just "!include conf.d/*.conf".

It's strange that all the extra content (especially ssl conf) only
occurs in conf.d/10-ssl.conf.
To dig on what's happening underneath I ran `strace doveconf -n 2>&1
|egrep "\.conf|conf\.d"` and got:

It seems that files in conf.d is never read before doveconf's
complaint! I have totally no idea why this happens. Any help?
