Question

I am using wso2esb-4.8.1 with java web client.
I wish to do SSL mutual authentication in wso2esb.My client web as well as android app so i followed http://pathberiya.blogspot.in/2012/08/enable-mutual-ssl-for-proxy-services-in.html above blog so i created .jks file and replaced with wso2carbon.jks its working.
But how to do mutual authentication with back end server .It has its own certificate .Can i export that certificate into my wso2esb security folder.In that way is it work or not.Else i need to use same certificate with back end also help me for this.

Answer 1

Mutual authentication is not currently supported for proxy -> backend communication. See JIRA issue here.

What you need is to enable custom SSL profiles in the axis configuration. For a specific endpoint, you can specify which keystone and which truststore to use. See this post: http://nadeeshaan.blogspot.nl/2014/03/enabling-custom-ssl-in-wso2-esb-4.html
