503 error - AuthenticationSupport service missing. Cannot authenticate request.

[shubhi_mishra]

I uninstalled LiveCycle from my windows machine and restarted it. Now when I try to start CQ6 I get this error when trying to load up any page. Even http://localhost:4502

Problem accessing /. Reason:

    AuthenticationSupport service missing. Cannot authenticate request.

I see the following in my error.log

01.05.2015 22:27:24.577 *ERROR* [FelixStartLevel] com.adobe.granite.repository.impl.SlingRepositoryManager start: Uncaught Throwable trying to access Repository, calling stopRepository() java.lang.IllegalStateException: Segment 55c759a2-2ced-4d9e-af48-45209e6aa829 not found at org.apache.jackrabbit.oak.plugins.segment.file.FileStore.readSegment(FileStore.java:541) at org.apache.jackrabbit.oak.plugins.segment.SegmentTracker.getSegment(SegmentTracker.java:106) at org.apache.jackrabbit.oak.plugins.segment.SegmentId.getSegment(SegmentId.java:97) at org.apache.jackrabbit.oak.plugins.segment.Record.getSegment(Record.java:68) at org.apache.jackrabbit.oak.plugins.segment.MapRecord.getEntry(MapRecord.java:138) at org.apache.jackrabbit.oak.plugins.segment.MapRecord.getEntry(MapRecord.java:170) at org.apache.jackrabbit.oak.plugins.segment.SegmentNodeState.hasChildNode(SegmentNodeState.java:326)

How can I resolve this? I can't even access any pages!

Check whether your Apache Sling Authentication Service Bundle is active or not. You can check at localhost:4502/system/console/bundles, if it is not active then try to activate it manually.

If the bundle is active and you still get the issue then other solution is to re-index your repository.

Refer to following article for How to re-index AEM Repository: http://www.wemblog.com/2011/12/how-to-rebuild-index-in-cq5-wem.html

Hello Team,

I am facing exactly same problem as above. I am thinking to re--index my repository but I am unable to access crx/de..It says service unavailable.

How do I move forward ?

Thanks,

Vish

Hi,

the error is a symptom of a problem in your repository. Most likely during startup there was an exception much earlier, if you find the original exception, it will help you determine the root cause.

For future visitors, Deleting repoinit folder from my AEM instance fixed this issue for me. Either you can run below command

 rm -rf crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit OR delete the folder manually.

This worked for me

this breaks crx/de and several configurations 
Needs a reindexing afterwards!
