Distribution Release: Univention Corporate Server 4.4-3

  • Univention Corporate Server (UCS) is an enterprise-class distribution based on Debian GNU/Linux. The project’s latest release is an update to the distribution’s 4.4 series: 4.4-3. “With this release, we have found a solution to three challenges: first, we fixed problems with upgrading Docker which occurred in older UCS installations. These had led us to delay the update to UCS 4.4-2 for some environments and to extend the maintenance of UCS 4.4-1 in order to give all users sufficient time to perform updates. Less common, but all the trickier were two other cases. With some Samba 4 shares, newer versions of Windows Explorer could crash when accessing the security settings. This was caused by extended file system permissions in connection with local user accounts not stored in LDAP. From this Samba generated status codes unknown to Windows. The second and similarly difficult to pinpoint case in an Open Source software used by us was a startup problem of OpenLDAP, which only occurred with a very rare constellation of contents at the end of the database file. We were able to isolate both problems, solve them in UCS and make patches available to the OSS projects.” Additional information can be found in the distribution’s release announcement.
