When a Kerberos subsystem is defined in the authentication chain it is not possible any more to retrieve the CMIS AtomPub Binding.
Steps to reproduce
1- Install Alfresco 4.2 with Kerberos authentication enabled in the authentication chain
2- Start Alfresco
3- With Curl request the CMIS AtomPub bindings :
curl -v --user admin:admin http://localhost:8080/alfresco/cmisatom
CMIS AtomPub bindings are retrieved as the result stream of the request
A status code 200 is sent back but the result stream does not contain CMIS AtomPub bindings.
When using an Apache Chemistry Client the following exception is sent when the repository is retrieved : "CmisConnectionException: Unexpected document! Received: something unknown"
