do I need upgrade with using EAP-SIM?

[Alex Wang]

Hi~   My radius server is running freeradius-0.9.3 right now, and I wish that could support the EAP-SIM. What should I do? Using the snapshot version to take place the 0.9.3? or just only need to add a new module?   In addition, when the authencation mechanism is EAP-SIM, is there any difference between to be a home server and to be a radius proxy server in config, modules, or something else?   thanks a lot   alex
