I have a requirement to consume Dynamics GP native web service from Java and i am using Apache CXF to create the soap client. We are using kerbaros authentication as part of CXF (spnego).
We are able to call the web service from a .net based soap client from the same computer by passing the username, password and domain name as input for authentication.
But with java.. we are getting SocketTimeoutException as below.
[Krb5LoginModule] authentication failed
org.apache.cxf.interceptor.Fault: General security error (An error occurred in trying to obtain a TGT: Receive timed out)

We have login.config and krb5.conf files as below.
