Symptom

Diagnostics/Test

Use of Incompatible Crowd libraries

Check what version of Crowd does the Confluence instance have in confluence's WEB-INF/lib ?
Crowd will be fine at version 1.1.1, it is the client code that needs to be running at the later version 1.1.2.

Reference: http://confluence.atlassian.com/display/CROWD/3.2.3+Integrating+Crowd+with+Atlassian+Confluence step 2.1.1

Use {{ ls -lah crowd}} inside the WEB-INF/lib folder to list the current libraries

~~rw-r~~r- 1 ... 54K Oct 1 20:54 crowd-atlassian-user-1.1.2.jar
~~rw-r~~r- 1 ... 285K Oct 1 20:54 crowd-core-1.1.2.jar

atlassian-user.xml does not conform to 2.2.2

[user.configuration.xml.XMLConfigurationParser] instantiateProcessor Could not instantiate proces
com.atlassian.crowd.integration.atlassianuser.CrowdRepositoryProcessor [java.lang.NoClassDefFoundError: com/atlassian/user/configuration/AbstractRepository

The error above implies that the XML parser that reads the atlassian-user.xml encountered a problem, syntaxtic, with the atlassian-user.xml file.

Root Cause

Version Incompatibity
Currently Crowd supports centralised authentication and single sign-on (SSO) for Confluence versions 2.5.6 and later with Crowd 1.1.2 and later.
http://confluence.atlassian.com/display/CROWD/3.2.3+Integrating+Crowd+with+Atlassian+Confluence
Confluence version 2.6 require use of 1.1.2 and Crowd 1.1.1 libs (client)

atlassian-user.xml validity

Up to the version 2.5.6 of Confluence user had to add the Crowd classes to the atlassian-user.xml file to specify the correct source of the repository.
Edit the CONFLUENCE/confluence/WEB-INF/classes/atlassian-user.xml file so that the contents of the file is:

<repository key="crowd" class="com.atlassian.crowd.integration.atlassianuser.CrowdRepository">
<classes>
<processor>com.atlassian.crowd.integration.atlassianuser.CrowdRepositoryProcessor</processor>
<userManager>com.atlassian.crowd.integration.atlassianuser.CrowdUserManager</userManager>
<groupManager>com.atlassian.crowd.integration.atlassianuser.CrowdGroupManager</groupManager>

<authenticator>com.atlassian.crowd.integration.atlassianuser.CrowdAuthenticator</authenticator>
<propertySetFactory>com.atlassian.crowd.integration.atlassianuser.CrowdPropertySetFactory</propertySetFactory>
<entityQueryParser>com.atlassian.crowd.integration.atlassianuser.CrowdEntityQueryParser</entityQueryParser>
</classes>
</repository>

Since the 2.5.6 release, only the following Crowd repository name is required.

Solution

I have found that crowd is not version 1.1.2, it is running 1.1.1. The jars are version 1.1.2.

get the correct libraries
ensure there are no duplicate libraries in the WEB-INF/lib

You can see a situation where you have Crowd 1.1.1 running with the crowd-* 1.1.2 libs and experiencing a problem.

In this case the atlassian-user.xml could be the culprit.
