Scope
The development of UCS 3.0 is focused on the following topics:
Debian basis
UCS 3.0 is based on Debian 6.0 "Squeeze". The whole debian repository except the section "games" will be provided. The seperation into maintained (will be distributed on the DVD) and unmainted will be remained. UCS 3.0 will be more up to date than Debian Squeeze, e.g. applications like Mozilla Firefox, Samba and OpenLDAP.
UCS 3.0 will use Linux kernel 2.6.32. Furthermore, it will support IPv6. Normal users will not be able to login to a domain controller anymore.
Installer
The UCS installer in UCS 3.0 will be reduced to the essentials. Configurations after the installation will be made with single UMC modules. The automated installation can still be made with installation profiles.
Samba 4
Samba 4 offers full Microsoft Active Directory functionality and can be managed by the common Microsoft Active Direcotry tools. UCS 3.0 will include Samba 4 und Samba 3 will still be distributed.
UCS management system
The UCS management system (UDM/UMC) has a lot of grown structures and uses different technologies. The whole web-based frontend of the UCS management system with ajax functionality for UCS 3.0 will be rewritten on the basis of the dojo javascript library. Performance and usability will be improved a lot. The backend will be remained and can be used in the shell or in scripts as usual.
Virtualization
The begun path on virtualization supporting the hypervisors KVM and Xen will be continued. In UCS 3.0 the virtualization technology Xen will be updated to version 4.1.
Kolab and Email
The "Kolab for UCS" packages from Univention will be removed in UCS 3.0. The Univention technology partner Kolabsystems AG will deliver certified "Kolab for UCS" packages instead. The standard email stack consisting of Cyrus IMAP, Postfix, Spamassassin/Amavis and Horde 4 will be updated.
Fax
Hylafax will remain in the "maintained" section and is distributed with UCS 3.0. The existing integration into the configuration infrastructure will be removed. Customers and partners can fall back on their standard know how for Hylafax. A tutorial for the configuration of Hylafax in UCS will be provided in this wiki.
Nagios
UCS 3.0 will include Nagios 3.
Desktop in UCS 3.0
UCS 3.0 will include a desktop consisting of KDE 4 and other software updates. It will be a pre-version of Univention Corporate Server (UCD) 3.2.
Removed from UCS 3.0
The following parts will be removed from UCS 3.0 or replaced by alternatives:
- UCS 2 has distributed and integrated a thin client component. It will be removed in UCS 3.0 and has already been replaced by the product UCS Thin Client Services.
- UCS 2 includes a Windows installer that provides an environment for full-automated installations of various Microsoft Windows versions. This component will be removed in UCS 3.0. Alternative solutions for Microsoft Windows software provisioning can be used for the automatic installation of Microsoft Windows systems.
- unidump will be removed, as well. Alternatively, Bacula is recommended for a backup solution in UCS 3.0.
- "Custom Attributes" for user-definied attributes will no longer be supported in Univention Directory Manager from UCS 3.0 on. If present, they have to be updated to "extended attributes" (see also Update Custom Attributes to Extended Attributes.
