context initialization failed: NullPointerException

decolnets — Thu, 09 Jul 2009 12:39:38 GMT

Hi all,I'm a quite new in alfresco and I use the Community 3.2 on a Windows XP. I'd like to use the active directory of my enterprise for the authentication on this system. For that, I configure alfresco to use kerberos with a realm connected to the AD.But I received an error during initialization a

It looks like the authenticationContext on one or more of your authentication components is not set (new property in v3.2). I'm not sure why. Are you running with any custom Spring configuration? If so, what?

Facing same problem.
I have extracted chaining-example.zip into extension folder and later on removed chaining-jaas-authentication-context.xml and chaining-ntlm-authentication-context.xml since I only want LDAP and Alfresco defaults. I also replaced LDAP properties with those that match my environment.

Now I have:

C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes
-alfresco-global.properties Modified with authentication.chain=alfrescoNtlm1:alfrescoNtlm,ldap1:ldap

C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes\alfresco\extension
-chaining-authentication-context.xml
-chaining-alfresco-authentication-context.xml
-chaining-ldap-authentication-context.xml
-ldap-authentication.properties

C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes\alfresco\extension\Authentication\ldap\ldap1
-ldap-authentication.properties

Any clue ?

Thanks in advance

Where did you get chaining-example.zip from? This is not valid for Alfresco v3.2.

Hi dward

It comes with my alfresco installation -Alfresco-Community-3.2-Full-Setup.exe- , it is inside the extension folder.
%ALF_HOME%\tomcat\shared\classes\alfresco\extension
However I will check those files looking for an error.

Thanks for your quick reply

Oh dear. We'll need to remove those files from the distribution. Can you please read the subsystems Wiki

http://wiki.alfresco.com/wiki/Alfresco_Authentication_Subsystems#Configuring_the_Authentication_Chain

You will notice that there is no need to copy / edit Spring configuration in the extensions directory in order to set up an authentication chain. Please remove these obselete files.

Thanks again. I won't be confused again with those files. I have tried this way because I couldn't configure Authentication subsystem properly. I have copied ldap-authentication properties to:

C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes\alfresco\extension
C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes\alfresco\extension\Authentication\ldap
C:\desarrollo\java\install\alfresco-3.2\tomcat\shared\classes\alfresco\extension\Authentication\ldap\ldap1

But it is still loading default properties:

See

Unfortunately, this bug was found in the Labs release that meant that the extension classpath mechanism for overriding properties was not working

https://issues.alfresco.com/jira/browse/ETHREEOH-2478

If you are only controlling one subsystem, just put its properties in alfresco-global.properties. Otherwise you will need the nightly build from 14th July.

Thanks

Dave

Thanks again

Seems it is loading correct values now -putting them in alfresco-global.properties-. However I cannot login but I think now is a problem with my LDAP (Apache).

Thank you very much for your help

Kind Regards

Just checking … can anyone confirm that the mechanism is or is not working in the nightly build of the community edition?
(https://issues.alfresco.com/jira/browse/ETHREEOH-2478 says it is solved for 3.2 Enterprise).

I tried yesterday's nightly build, but I still have to use a workaround.
