Univention Corporate Server 5.0-6

In the last three months we have released 47 security updates, most of them from the Debian base distribution. However, we have also fixed security-relevant errors in the Univention packages, e.g. password leaks via the process list. We have also further stabilized the Univention Management Console (UMC) when connecting to the individual UMC modules. We have improved the way the Univention Directory Manager (UDM) handles inconsistent user capitalization. Some data is now updated atomically by the portal, which avoids certain error patterns, and the self service now translates the forms correctly in all cases.
