Guys, allow me to reopen this thread again, and this time the authentication is back again 
The situation I’m facing is to send send SOAP messages over HTTPS, with client-certificate authentication. Some people call this as mutual authentication, which seems appropriate.
I’m aware that we can configure IS on provide many client-certificates, and also setup server alias to supply a specific certificate for each target server, but this seems to be valid the context of invoking services at another IT (the pub.remote:invoke).
Does this (the ability to manage multiple client-certificate and supply separate certificates for each different web server) also applies to pub.client.http and pub.client.soapHttp?
Regards,
