invalid login attempts user lockout

Hi All, Does anyone know of RadiusServer denying access for a particular user after a configurable number of invalid login attempts. I know this can be done on the client side with pam modules. But i thought since radius users are same across multple nodes connected to radiusserver, it would be an useful option to lockout at radius server level. Please let me know if anyone is aware of this scenario. Regards, Pavan.
