Univention Corporate Server 3.2 erratum 48 (bugfix)

This update fixes the following issues:
* The handling of DNS timeouts in univention-ad-takeover has been improved 
* The sync mode is now configurable through UCR. for every connector property 
  (such as users, groups, containers etc.)
* A problem in the handling of non-English user and group names was fixed
  in univention-ad-takeover. If the well known users and groups in AD are
  found to be non-English during takeover, the corresponding objects will be
  renamed in UCS to match.
* Added support for synchronisation of MS WMI filters (disabled by default).
* The internal connector status database is now removed when re-joining
  the system.
