Description

When using the kolab binary in a virtual environment such as LXC, Python throws an exception for not having read access to /proc/sys/net/ipv4/tcp_keepalive_time. This is causing issues in pykolab/imap/__init__.py line 851.

pykolab-0.8.7-1.1.el7.kolab_wf.noarch

Reproduce: Run Kolab within an LXC container. (This exact environment is running on ProxmoxVE).

..... AND I have no good way to provide code... so Github it is!

https://github.com/cdp1337/pykolab/commit/76d97e82d17519f914d04ec7a6338831807227c8

Looks like the commit rP927dce48ba8566d20b08a8392943dc23b8aebcc5 broke this on LXC, and subsequently broke the build. (B7239)

Anyway, the branch /dev/cdp1337/T2049 on github has the fix and it's working now for me.

(Actually, setting this to open until the upstream code gets fixed; may be a good idea) Resolved elsewhere, still a problem upstream.

Just updated to Kolab 16.0.1 Release 12.1.el7.kolab_wf that this is still an issue when running in an LXC host!

If there is a patch for Winterfell could you please port this also to Kolab16?
I have a current Kolab16 installation in a Centos7 lxc container on an Ubuntu 16.04 host.
kolab lm is not working and there are no folders created for new users.
