RE: Giving Up on Alfresco Portlet LDAP Integration..

Mika Koivisto:

My advice is to forget about alfresco. It really doesn't deliver on its promise. Depending on what you really need just plain Liferay could be enough.

We've used Alfresco for little over a year and now we are getting rid of it due to scalability issues and poor response times. My issues are specifically related to Alfresco's JCR API and it's rather poor implementation.

Hi Mika,

Yes, Alfresco definitely has issues, especially regarding JCR: it just plain isn't JCR compliant, and cannot be without serious rework. I'd point you to their JIRA issue 706 (they've since renamed them) wherein they describe dropping JCR compliance due to issues with their own ThreadLocal use and their use of Acegi, which also works via ThreadLocals, and how they cannot service more than a single concurrent request from a user due to these issues. This is obviously a problem in a web environment where browsers other than IE commonly use 4 or more concurrent threads to request content for a page.

Regarding Liferay's Journal CMS: You cannot reliably utilize the import/export features for content. That's a pretty big problem for me. We're working on this issue.

I've been really disappointed with Alfresco and it's so called open source model where they only give you access to their trunk.

Giving Up on Alfresco Portlet LDAP Integration..

2008-08-13T12:30:56Z

Hi all,

I've been working on this for almost 3 weeks and failed
My objective is to do full integration using CAS, ApacheDS, Liferay 5.0.1 and Alfresco Portlet (I've downloaded alfresco-portlet-5.0.0.1.war). I've posted at Installation/Setup Thread but no one had replied

1. Success LDAP integration on Alfresco Standalone
==================================================
I've downloaded alfresco-community-tomcat-3.0.0dev. Configured ldap-authentication.properties and ldap-authentication-context.xml with simple configuration.

2. Failed LDAP integration on Alfresco Portlet as plugin to Liferay
===================================================================
I copied the working files (ldap-authentication.properties and ldap-authentication-context.xml). StartUp tomcat and got errors related to repository and jlan. I copied alfresco-repository.jar and alfresco-jlan-embed.jar. Now I got below errors:

I really hope someone out there can help me out on this.. Else I'll just give up..
Is't really impossible to do so? I've been reading few tips/How To. They sound simple and strait forward.. I've tried but still failed...
