Hi,

as soon as I set

server.conf
[sslConfig]
requireClientCert = true

I can see these entries in splunkd.log:

Splunkd.log 
01-28-2014 13:31:55.120 +0100 ERROR TcpInputFd - SSL Error = error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate 
01-28-2014 13:31:55.120 +0100 ERROR TcpInputFd - ACCEPT_RESULT=-1 VERIFY_RESULT=0

and DBConnect JBridge server stops working:

This config unfortunately not yet supported and code change is estimated to be delivered in next major version of DBConnect.
