+ * Declarations for kdcpolicy plugin module implementors.
+ *
+ * The kdcpolicy pluggable interface currently has only one supported major
+ * version, which is 1.  Major version 1 has a current minor version number of
+ * 1.
+ *
+ * kdcpolicy plugin modules should define a function named
+ * kdcpolicy_<modulename>_initvt, matching the signature:
+ *
+ *   krb5_error_code
+ *   kdcpolicy_modname_initvt(krb5_context context, int maj_ver, int min_ver,
+ *                            krb5_plugin_vtable vtable);
+ *
+ * The initvt function should:
+ *
+ * - Check that the supplied maj_ver number is supported by the module, or
+ *   return KRB5_PLUGIN_VER_NOTSUPP if it is not.
+ *
+ * - Cast the vtable pointer as appropriate for maj_ver:
+ *   maj_ver == 1: Cast to krb5_kdcpolicy_vtable
+ *
+ * - Initialize the methods of the vtable, stopping as appropriate for the
+ *   supplied min_ver.  Optional methods may be left uninitialized.
+ *
+ * Memory for the vtable is allocated by the caller, not by the module.
