Class KerberosCallbackHandler

java.lang.Object

com.mulesoft.mule.runtime.gw.client.httpclient.krb5.KerberosCallbackHandler

All Implemented Interfaces:

CallbackHandler

public class KerberosCallbackHandler
extends Object
implements CallbackHandler

This is a Kerberos-specific LoginContext CallbackHandler used to inject the default LoginContext for the Kerberos auth.
Per JavaSE javax auth API spec, this injection/override applies on the following cases (see below, ours falls in the 2nd category):
- If the constructor has a CallbackHandler input parameter, the LoginContext uses the caller-specified CallbackHandler object.
- If the constructor does not have a CallbackHandler input parameter, or if the caller specifies a null CallbackHandler object (and a null value is permitted), the LoginContext queries the auth.login.defaultCallbackHandler security property for the fully qualified class name of a default handler implementation. If the security property is not set, then the underlying modules will not have a CallbackHandler for use in communicating with users. The caller thus assumes that the configured modules have alternative means for authenticating the user.
- When the LoginContext uses the installed Configuration (instead of a caller-specified Configuration, see above), then this LoginContext must wrap any caller-specified or default CallbackHandler implementation in a new CallbackHandler implementation whose handle method implementation invokes the specified CallbackHandler's handle method in a java.security.AccessController.doPrivileged call constrained by the caller's current AccessControlContext.
