FreeRadius module

Hello all. I'm interested in include an authorization module in freeradius which will be executed after an authentication success, but before send the success message to the AP and the user. Can anybody help me telling me how to create a new module for freeradius? Thanks in advance. -- ----------------------------- Manuel Sanchez Cuenca Departamento de Ingenieria de la Informacion y las Comunicaciones Facultad de Informatica.
