How do I use AuthenticationManagerServiceClient with certificates

[Former Community Member]

I use a personal PKI cert and a truststore to authenticate via properties with ServiceClientFactory. I would like to make authentication transparent. I can get the users keystore and the systems truststore certificates programmatically (without reading files). It appears that I should be able to use the AuthenticationManagerServiceClient.authenticate(java.lang.String unsignedData, java.lang.String signatureValue) method. Does anyone have an example using this method?
