[Openswan Users] Radius client with Os 2.6.38

[Goffe, Don]

While I don't think this is an Os issue, I do value the opinion of this group.
Does anyone have an opinion as to which open source Radius would play nicely in our Linux 2.6 kernel and Openswan?
I need a client that can authenticate with our Verizon wireless carrier.

Thanks in advance.
