Update: kolab-webadmin 3.2.12 (Updated)

We’re pleased to announce a further update for the kolab-webadmin packages, version 3.2.12.

This update is a bugfix release for Kolab 16, available for CentOS 7, Debian 8, Debian 9, Red Hat Enterprise Linux 7 and Ubuntu 16.04.

While our previous release of the kolab-webadmin did resolve the issues mentioned in the errata, an old regression defect was sneaking into the final package. After update, the kolab-webadmin would show up with all fields grayed out and unavailable for change.

This regression was fast eliminated, and a new package created and released. If you update at this time, there is no such issue present.

We ask you to please accept our apologies for the inconvenience this has caused.

Increase Web Client Performance with Memcache

Memcache is a protocol to access a simple key-value store, that is memory-backed, over a network socket. The memcached server does not perform any form of access control and is optimal for certain caches used in the Kolab web client (and associated HTTP-based access interfaces), by avoiding superfluous login, access control, and other such software policy considerations, as well as disk I/O.

This article outlines the installation and configuration of a single memcached server for use with the Roundcube web client for Kolab.
