Authentication with Talend ESB
Authentication can be enabled for the Atom REST interface of the TESB Authorization XACML
         Policy Registry by editing the container configuration file
            etc/org.talend.esb.authorization.xacml.registry.service.cfg. The
         content of this file is as
         follows:
      # Authentication method BASIC,NO
pap.authentication = NOSetting pap.authentication to BASIC means that REST clients of the registry must use HTTP Basic Authentication to call the registry. Credentials are authenticated using JAAS.
After authentication is enabled, you need to configure the communication between PDP and
         the authorization registry in the etc/org.talend.esb.authorization.pdp.cfg
         file:
      # Authentication method BASIC,NO
authentication = NO
username = karaf
password = karafChange the authentication value to BASIC so that PDP can read policies from the registry.
