/usr/lib/cyrus-imapd/reconstruct

It seems that the 3.16 kernel upgrade for debian 8 breaks lxc for kolab on centos7. I have tested with debian 9 running a centos7 container for kolab and everything works.

T2094 https://git.kolab.org/T2094 says this is a known lxc problem and is fixed, but it does not work for me

I mounted the /proc filesystem rw in the container config by setting

lxc.mount.auto = proc:rw

in my container config

now my tcp config is ok but cyrus has an auth failure:

[root@shiraz ~]# kolab list-mailboxes

when I try kolab list-mailboxes, I get a crash:

[root@shiraz kolab-webadmin]# kolab list-mailboxes

I am running centos7 in an lxc container on Debian Jessie.
sysctl.conf has net.ipv4.ip_nonlocal_bind = 1 on the debian host

@sibio guam works ok, no errors. I don't think it is guam related.

In my understanding, guam filters out imap requests for groupware folders from non-groupware clients like plain thunderbird so users don't delete the Calendar folder accidently.

I think that kolab would directly create the mailboxes via the command line rather than imap. Anyway, I can create folders from Kontact, so I don't think that is the issue.

Raynald, it has not been working for a couple of weeks so It's not the port issue for cyradm. I needed cyradm to find if the mailbox was being created and your post was very timely.

Hello All, My Kolab16 on Centos7 is no longer creating shared folders from the web interface.

There are no errors reported in the web interface and I cannot find anything in the logs. I have checked Cyrus from the cyradm (thanks Sibio) tool and the mailbox is not created.

Does anyone have any suggestions how to find the problem?

thanks Marko

Thanks Sibio & Timotheus - working for me as well

I'm seeing this problem too.
