Dave Ward d2180c5eaa Refactor subsystems for authentication chaining
- An authentication chain of size 1 configured by default
- DefaultChildApplicationContextManager supports dynamic configuration of the authentication chain via Spring or JMX. Any number of instances of any type allowed in chain.
- SubsystemChainingAuthenticationComponent and SubsystemChainingAuthenticationService iterate across configured chain for Authentication
- SSO (NTLM / Kerberos) and CIFS authentication independently activatable for any component in chain (where supported).
- SubsystemChainingProxyFactory used to proxy directly to first active CIFS authenticator or SSO filter in the chain
- CIFS server knows not to bother starting if authentication chain doesn't have an active CIFS authenticator (e.g. LDAP only)
- Rationalization of subsystem configuration folder structure and JMX object naming
- Classpath based extension mechanism for community edition - alfresco/extension/subsystems/<category>/<typeName>/<id>/*.properties in classpath can be used to configure specific subsystem instances
- Simplification of JMX infrastructure. No longer Spring bean definition based, thus allowing dynamic creation/registration of new instances at runtime.
- New AuthenticationChainTest unit test
