Simple Kerberos client in Java?

Question

Applications such a Google\'s Chrome and IE can transparently handle Kerberos authentication; however I can not find a \"simple\" Java solution to match this transparency. A

Answer 1

Oracle has an example using Java's SaslClient. I'm not a Java programmer, but when I pointed this out once to someone who is, they were able to make it work pretty quickly. It may still require a "conf" file somewhere (n.b. Kerberos uses environment variables, often starting with KRB5_, to know where to look for such files). Also note that Kerberos itself does not include a transport of any kind--your app needs to know how to send and receive the Kerberos payloads the way the server expects (and this is different depending on the server you are trying to authenticate with).
