------------------------------------------------------------------------------------------------------------------------ We are proud to a announce another alpha release of Samba 4. What's new in Samba 4 alpha10 ============================ Samba 4 is the ambitious next version of the Samba suite that is being developed in parallel to the stable 3.0 series. The main emphasis in this branch is support for the Active Directory logon protocols used by Windows 2000 and above. Samba4 alpha10 follows on from the alpha release series we have been publishing since September 2007 WARNINGS ======== Samba4 alpha10 is not a final Samba release. That is more a reference to Samba4's lack of the features we expect you will need than a statement of code quality, but clearly it hasn't seen a broad deployment yet. If you were to upgrade Samba3 (or indeed Windows) to Samba4, you would find many things work, but that other key features you may have relied on simply are not there yet. For example, while Samba 3.0 is an excellent member of a Active Directory domain, Samba4 is happier as a domain controller, and it is in this role where it has seen deployment into production. Samba4 is subjected to an awesome battery of tests on an automated basis, we have found Samba4 to be very stable in it's behaviour. We have to recommend against upgrading production servers from Samba 3 to Samba 4 at this stage, because there may be the features on which you may rely that are not present, or the mapping of your configuration and user database may not be complete. If you are upgrading, or looking to develop, test or deploy Samba4, you should backup all configuration and data. NEW FEATURES ============ Samba4 supports the server-side of the Active Directory logon environment used by Windows 2000 and later, so we can do full domain join and domain logon operations with these clients. Our Domain Controller (DC) implementation includes our own built-in LDAP server and Kerberos Key Distribution Center (KDC) as well as the Samba3-like logon services provided over CIFS. We correctly generate the infamous Kerberos PAC, and include it with the Kerberos tickets we issue. The new VFS features in Samba 4 adapts the filesystem on the server to match the Windows client semantics, allowing Samba 4 to better match windows behaviour and application expectations. This includes file annotation information (in streams) and NT ACLs in particular. The VFS is backed with an extensive automated test suite. A new scripting interface has been added to Samba 4, allowing Python programs to interface to Samba's internals. The Samba 4 architecture is based around an LDAP-like database that can use a range of modular backends. One of the backends supports standards compliant LDAP servers (including OpenLDAP), and we are working on modules to map between AD-like behaviours and this backend. We are aiming for Samba 4 to be powerful frontend to large directories. CHANGES SINCE alpha9 ===================== Alpha9 was released last week, but in the time since the release we have found and fixed two important segfaults, and improved the experimental DRS replication. CHANGES ======= Those familiar with Samba 3 can find a list of user-visible changes since that release series in the NEWS file. KNOWN ISSUES ============ - Domain member support is in it's infancy, and is not comparable to the support found in Samba3. - There is no printing support in the current release. - There is no NetBIOS browsing support in the current release - The Samba4 port of the CTDB clustering support is not yet complete - Clock Synchronisation is critical. Many 'wrong password' errors are actually due to Kerberos objecting to a clock skew between client and server. (The NTP work in the previous alphas are partly to assist with this problem). - The DRS replication code often fails, and is very new - Users upgrading existing databases to Samba4 should carefully consult upgrading-samba4.txt. We have made a number of changes in this release that should make it easier to upgrade in future. Btw: there exists also a script under the "setup" directory of the source distribution called "upgrade_from_s3" which should allow a step-up from Samba3 to Samba4. It's not included yet in the binary distributions since it's completely experimental! - ACL are not set by default on shares created by the provision. Work is underway on this subject and it should be fixed in Alpha10. RUNNING Samba4 ============== A short guide to setting up Samba 4 can be found in the howto.txt file in root of the tarball. DEVELOPMENT and FEEDBACK ======================== Bugs can be filed at https://bugzilla.samba.org/ but please be aware that many features are simply not expected to work at this stage. The Samba Wiki at http://wiki.samba.org should detail some of these development plans. Development and general discussion about Samba 4 happens mainly on the #samba-technical IRC channel (on irc.freenode.net) and the samba-technical mailing list (see http://lists.samba.org/ for details). ================ Download Details ================ The release tarball is available from the following location: * http://download.samba.org/samba/ftp/samba4/samba-4.0.0alpha10.tar.gz This release has been signed using GPG with Andrew's GPG key (28B436BB). * http://download.samba.org/samba/ftp/samba4/samba-4.0.0alpha10.tar.asc To verify that the signature is correct, make sure that the tarball has been unzipped and run: $ gpg --verify samba-4.0.0alpha10.tar.asc Happy testing!

Notice of this event has already been posted through the normal OASIS outlets and I am forwarding this just a as reminder. Regards John Borras Chair OASIS eGOV MS Steering Committee m. +(0)44 7976 157745 Skype: gov3john ____________________________________________________________________________ _____________ From: monica.palmirani [ moni ... @unibo.it ] Sent: 14 July 2010 22:04 To: John Borras Subject: Summer School LEX2010 Dear John Borras, I am associate professor of "ICT and Law" in the University of Bologna (see my website http://www.unibo.it/SitoWebDocente/default.htm?wbc_purpose=basic?mat=34488 ) and now I am in Stanford for a visiting professorship. I would like to notify you our Summer School LEX2010, already announced by OASIS, concerning the XML applied in Legal domian for enhancing the eGov applications. I am asking you to make a short announcement on this initiative in your OASIS eGov web site, because our target is mostly the public administrations, technical and not technical people in charge to take decision on innovation in eGov domain. The summer school web site is http://summerschoollex.cirsfid.unibo.it and in attachment you can find a short description of the initative, that you can send in your mailing-list. Best regards, Monica Palmirani Legislative XML Summer School LEX10 *Managing Legal Resources in the Semantic Web* 6-11 September 2010 – Ravenna, Italy, Faculty of Law, via Oberdan 1. http://summerschoollex.cirsfid.unibo.it/ Overview and Aim ====================================================== The school aims at providing knowledge of the most significant ICT standards emerging for legislation, judiciary, parliamentary and administrative documents. The course provides an understanding of their impact in the different phases of the legislative and administrative process, awareness of the tools based on legal XML standards and their constellations, and the ability to participate in the preparation and use of standard-compliant documents throughout law-making process. In particular we would like to create consciousness in the stakeholders in the legal domain about the benefits and the possibilities provided by the correct usage of the Semantic Web technologies like XML standards, ontologies, natural language techniques applied to the legal text, legal knowledge modelling and reasoning. Target ====================================================== LEX is designed primarily for officers of legislative bodies and other normative authorities (at the national, international, regional and local level), but its target group also includes clerks, drafters of normative texts in the private sector, digital library operators, private publishers in the legal domain, documentalists dealing with legal sources,administrative directors, eGov managers, technical director in the public administration, responsible of the dematerialisation in the public administration, technical responsible of the document management content, students and researchers working in legal informatics and legislation studies. Programme ====================================================== The Summer School is organized in two courses: ** A Basic Course providing an introduction to the XML web technologies and the basic level of the technologies for drafting and managing standard-compliant legislative and legal documents; ** An Advanced Course on the higher levels of the semantic web technologies as applied to the legal domain: modelling modifications, procedures and legal knowledge. LeX is an intensive, 6-day program, 8 hours for day, that requires participants' total dedication and intellectual commitment. Good management of legal documents involves at least six aspects: ** Drafting methods, to improve the language and the structure of legislative texts; ** Legal XML standards, to improve the accessibility and interoperability of legal resources; ** Legal ontologies, to capture legal metadata and legal semantics; ** Legal Knowledge extraction using natural language techniques; ** Formal representation of legal contents, to support legal reasoning and argumentation; ** Workflow models, to cope with the lifecycle of legal documents. Fees and application form ====================================================== For the full programme see the web site: http://summerschoollex.cirsfid.unibo.it/ where you can find also the application form, the fees and the scholarships for students.
