Announcement: IT Sistemi – SCOM Management Pack for Alfresco

July 21st, 2010 Ivan Pleština

IT Sistemi – SCOM Management Pack for Alfresco on Unix is designed to work with Alfresco Enterprise installations that are deployed on Unix-derived platforms which include popular Linux distributions like Red Hat Enterprise Linux, Novell SUSE, or CentOS. Management pack can be configured to monitor remote Alfresco deployments so this management pack can also be used to monitor Alfresco installations deployed on Microsoft Windows operating system.

Management pack is available for free to all interested customers for a limited time period. Beta version of this management pack expires on October 1st and it will stop functioning on that date. Please note that we left out some functionality that is not working at the moment or we otherwise found it not ready for the public distribution at the moment. To get all the management pack features you will need to monitor Alfresco Enterprise version due to Alfresco Community version limitations.

You can download the IT Sistemi – SCOM Management Pack for Alfresco on Unix by filling out the request form on the IT Sistemi website. Installation instructions are included with the download. (more…)

Alfresco 3.3g installation on CentOS 5.5 64-bit Linux server

June 26th, 2010 Ivan Pleština

The following guide will show you how to install a CentOS 5.5 64-bit Linux server based Alfresco ECM server. CentOS Linux distribution is amongst the most popular ones for its well known binary compatibility with major commercial Linux distribution Red Hat Enterprise Linux. CentOS is pretty much same as RHEL only without Red Hat’s vendor branding and artwork. Major reasons why you want to use CentOS over some other free Linux distributions is its stability and what’s most important hardware compatibility. Big hardware vendors like HP, Dell, or IBM tend to release Linux drivers for specific distributions only so choosing a distribution that is fully compatible with the USA-based and leading Linux vendor Red Hat is likely a smart move.

Now, important point to say is that Alfresco loves 64-bits so you want to install it on 64-bit hardware, operating system and use 64-bit Java Virtual Machine. While it certainly can work on 32-bit systems for production use I recommend that you use 64-bit system. Lets begin with Alfresco prerequisites.

Alfresco 3.3g integration with Active Directory and Google Docs

June 20th, 2010 Ivan Pleština

My last article on Alfresco integration with Active Directory brought up a lot of interest and what’s the most important positive feedback. That article is based on Alfresco Community version 3.2r2 so if you are using that version please continue reading that article.

This article will cover the latest community release 3.3g. On one hand I’m going to leave out most of the explanations that you can find in the original article and I’ll focus on getting things done in a focused article. You can also refer to the chapter 6 of the Professional Alfresco: Practical Solutions for Enterprise Content Management (Wrox Programmer to Programmer) [amazon.com] book or to the chapter 4 of the Alfresco 3 Enterprise Content Management Implementation [amazon.com] book.

Still, plan is to provide newcomers clear guides what has to be changed or to be more precise what is domain specific so I’ll make sure to insert “(domain specific property)” in code comments. Also, since version 3.3g supports document editing via Google Docs I’ll cover configuration of Google Docs integration as well. Again, I’ll repeat myself, for detailed explanation how stuff works refer to the original article as concept is the same. So let’s begin…

Afresco integration with Active Directory using Kerberos

March 21st, 2010 Ivan Pleština

After the first article about Alfresco’s integration with Active Directory has spurred a lot of interest I’ve decided to write a follow up article that shows how to use Kerberos for authentication. I’ll divide the article in three main parts:

  1. Description of Kerberos authentication process
  2. Setting up requirements for Kerberos implementation
  3. Alfresco configuration parameters for Kerberos

Alfresco – 2010 Roadmap

February 17th, 2010 Ivan Pleština

As some of you might have seen Alfresco team have published a roadmap for the year 2010. I must say I’m very pleased with the latest community version 3.2r2 (actually, couple more SVN releases than the official 17458 but lets not be picky). In my opinion, it is finally what was 3.0 “Stable” supposed to be and I’m not counting the DoD module here but the overall stability of the product.

My wishes for community edition in 2010:

  • content store selector available in enterprise edition only
  • better support for Windows 7
  • fine-tuning of UI controls in Share as some are really not available where they should be, hint: Edit Online on document details page
  • content modeling in GUI not just in XMLs
  • ability to chain SSO authentication with something non-SSO e.g. NTLM SSO + ldap if it is even technically possible
  • faster merging of bug-fixes from enterprise branch
  • better support from Alfresco team in forums though I must say they’ve been very helpful in last 6-9 months
  • publishing critical patches for last stable community release and not just telling people to “it’s in HEAD”
  • abandon policy to have certain functionality in enterprise edition only as legally possible

+ of course, everything they have in their published roadmap ;)

Alfresco, Sharepoint protocol, Office 2007, and Vista

January 24th, 2010 Ivan Pleština

To get the Alfresco’s implementation of Sharepoint protocol to work properly on Vista/Office 2007 with NTLM authentication you need to mess a bit with your registry. I consider you did your job and are using fully updated versions of both Vista and Office.

Open up the Alfresco Share, navigate to the document library and locate some Office document and click Edit online. Likely, the file will open read-only. So, implement this fix from Microsoft’s article KB 870853.

If you try again, file will open up fine but when you save it you’ll get an error message stating “Word did not save the document”. To fix this stop or disable the Web Client Windows service using Services MMC snap-in.

Sharepoint protocol should work completely now.

Deny delete permission to space owner in Alfresco

January 24th, 2010 Ivan Pleština

If you are the guy/girl responsible for implementing permissions model for your business case you might find yourself in trouble. Let us imagine a scenario where business case states that certain users should be able to create new content but not be able to delete anything. That’s the easy one, you’ll likely say, and assign Contributor role to those users.

Lets check Contributor role definition from the Alfresco wiki:

Contributor
Includes the Consumer permission group and adds AddChildren and CheckOut.
They will, by default own anything they create and have the ROLE_OWNER authority.

Hm, ROLE_OWNER looks suspicious:

“FullControl” granted to “ROLE_OWNER”
The owner (as defined by the ownable aspect, or, if the aspect is not present the node creator) is allowed all rights. This interacts with contributor for cm:content. They only need the right to create content in the default set up; all other rights come from the fact that they own the nodes they create.

To sum up the above, users that are just contributors can delete everything they create and you likely don’t want that.

So what can we do to fix this. There are two options and both have certain drawbacks. (more…)

Alfresco – Tomcat as a Windows service

November 8th, 2009 Ivan Pleština

Question that is often asked and that usually leaves new users puzzled is how to run Alfresco on Apache Tomcat 6 as a Windows service. Unlike most examples found on the Internet I’ll show you how to mostly use graphical interface instead of command line. This article assumes you have Alfresco Tomcat bundle extracted at C:\Alfresco and Java 6 installed at default location. (more…)

Alfresco integration with Active Directory

October 8th, 2009 Ivan Pleština

One of the main features of the Alfresco ECM System is the ability to integrate user authentication and synchronization with Microsoft Active Directory.

Unfortunately, integration is not trivial and it is error prone. While I’ll provide explanations how stuff works you can also have a look at the chapter 6 of the Professional Alfresco: Practical Solutions for Enterprise Content Management (Wrox Programmer to Programmer) [amazon.com] book or to the chapter 4 of the Alfresco 3 Enterprise Content Management Implementation [amazon.com] book.

In this guide I’ll show you how to achieve full integration with Active Directory which includes Alfresco Explorer and Alfresco Share SSO, CIFS SSO, and Active Directory (LDAP) users and groups synchronization. (more…)
