To tell the server to use your attributes for authentication, you must define your own Loadable Authentication Service (LAS), which is an NSAPI plugin. You load it into the server in the usual manner by adding the following directives to magnus.conf:
An Init directive that invokes the load-modules function to load the shared library.
An Init directive that calls the initialization function.
