SSL mutuo entre ESB y servicios de back-end no seguros, "cadena de certificaciones nulas"

wso2 wso2esb

Question

Estoy teniendo el siguiente error :

ERROR {org.apache.synapse.transport.passthru.SourceHandler} -  I/O error: null cert chain {org.apache.synapse.transport.passthru.SourceHandler}

al intentar habilitar el SSL mutuo entre mi servicio Proxy (personalizado) y 2 servicios back-end no seguros.

Esto es lo que hice hasta ahora:

1. Habilitado <parameter name="SSLVerifyClient">require</parameter>
2. Certificados públicos extraídos de 2 servidores back-end en [carbon_home] /respository/resources/security/wso2carbon.jks usando Java Key Tool:

keytool -export -keystore C: / I_T / WS02 / wso2 as-5.2.1 / repository / resources / security / client-truststore.jks -file C: / wssecurity / wso2 / wso2ASpublic.cert

3. Importó estos certs en la tienda de confianza de ESB:

   keytool -import -file C: / wssecurity / wso2 / wso2DSSpublic.cert -keystore C: / I_T / WS02 / wso2esb-4.8.1 / repository / resources / security / client-truststore.jks -storepass wso2carbon -alias wso2carbonDSS

4. Hecho lo mismo con el certificado de ESB en los clientes-almacenes de confianza del cliente.

Sospecho que los pasos 2-4 fueron innecesarios porque las tiendas de confianza ya contenían estos certs.

Quizás esto está causando los problemas?

Configuration :

(a) Change the following in the servers(server_home) to point to the new keystores/trustores.

In esb : Changed configuration files of the following files to point to the new keystores and their passwords (as above) :

                [server_home]/repository/conf/carbon.xml            
                [server_home]/repository/conf/axis2/axis2.xml   - also set  <parameter name="SSLVerifyClient">require</parameter>
                [server_home]/repository/conf/security/cipher-text.properties
                [server_home]/repository/conf/security/secret-conf.properties
                [server_home]/repository/conf/sec.policy

Restart server.

In soap , double click on the root project folder , navigate to WS-Security Configurations tab , then add the soapui_ts.jks as a TRUST store using soapui as the password. Then when you open a request in that project, in the Request Properties panel , set the previously configured soapui_ts.jks as the value for the SSL Keystore property.

Should all be good.
