Aki, you're a live saver! :). I hoped it would be something very simple.
Just couldn't find it.
This configmistake is the drawback of starting out with someone elses
cookbook and modifying it for your own use I guess.
I'll have another good look at the whole config for other mismatches.
Many, many thanks!

Hi!
You can't set
service imap {
service_count = 256
}
if you are using multiple system UIDs. See
https://wiki.dovecot.org/Services#imap.2C_pop3.2C_submission.2C_managesieve
*service_count* can be changed from 1 if only a single UID is used for
mail users. This is improves performance, but it's less secure, because
bugs in code may leak email data from another user's earlier connection.

Re: Fatal: setgid, imap connections dropped.
I'm still trying to fix this problem. Hopefully someone can help.
I've upgraded dovecot to 2.3.3
# dovecot --version
2.3.3 (dcead646b)
That didn't help.
Next I switched 10-auth.conf to use a local password file (instead of LDAP)
===
# cache all authentication results for one hour
auth_cache_size = 10M
auth_cache_ttl = 1 hour
auth_cache_negative_ttl = 1 hour
# only use plain username/password auth - OK since everything is over TLS
auth_mechanisms = plain
passdb {
driver = passwd-file
args = scheme=ssha username_format=%n /usr/local/etc/dovecot/passwd
}
userdb {
driver = passwd-file
args = username_format=%n /usr/local/etc/dovecot/passwd
}
==
The /usr/local/etc/dovecot/passwd file is in the following format
userA:{SSHA}hash:1000:1000::/home/userA
Authentication works, and mail gets delivered. But I'm still getting the
same intermitted errors.
Sep 28 00:03:24 mailserver dovecot: imap(userD)<14864>:
Fatal: setgid(1012(userD) from userdb lookup) failed with
euid=1011(userA), gid=1011(userA), egid=1011(userA): Operation not
permitted (This binary should probably be called with process group set to
1012(userD) instead of 1011(userA))
Also tried disabling the cache in 10-auth.conf, at no avail.
I'm a bit at loss :(

Fatal: setgid, imap connections dropped.
Hi,
I'm getting errors with my IMAP setup.
Basically, everything seems to work.
Mail is delivered nicely from Postfix to Dovecot via LMTP. Dovecot does
the authentication to LDAP (also for Postfix). Users are able to send mail
via authenticated submission (Postfix) and login into IMAP and POP.
However, IMAP connections are dropped frequently with an "ERROR:
Connection dropped by IMAP server.". After pressing reload on the webmail,
or refreshing in the client might help for a short period. So it fails
intermittently.
The errors in the maillog are below. It seems to be mixing up users kind
of randomly. I think when multiple connections are made at the same time.
Did a lot of searching, put couldn't find an answer to this problem. All I
can find is related to LDA, which I'm not using.
Any help would be appreciated.
