+/**
+ * The authentication manager takes care of the authentication process.
+ * Authentication happens on multiple threads. The conmgr thread parses
+ * the authentication request and passes it on to the authmgr thread. The
+ * authmgr thread invokes the (pluggable) authenticator to do the actual
+ * authentication. Then the response message is queued up to be delivered
+ * by the conmgr thread.
+ *
+ * <p> This structure prevents authentication to take place
+ * asynchronously, but in a controlled manner. Only one authentication
+ * will be processed at a time, but the dobj and conmgr threads will
+ * continue to operate independent of the authentication process.
