+     * In any case, if the delegation is not successful, the value returned
+     * by {@link GSSContext#getCredDelegState()} is false, and the value
+     * returned by {@link #getDelegPolicyState()} is also false.

+     * {@link #getDelegPolicyState() getDelegPolicyState} method. When
+     * delegation policy is not supported, <code>requestDelegPolicy</code>
+     * should return silently without throwing an exception.

+     * Note: for the Kerberos 5 mechanism, the delegation policy is expressed
+     * through the OK-AS-DELEGATE flag in the service ticket. When it's true,
+     * the KDC permits delegation to the target server. In a cross-realm
+     * environment, in order for delegation be permitted, all cross-realm TGTs
+     * on the authentication path must also have the OK-AS-DELAGATE flags set.
