EAP-TTLS with PAP

[Shriram Jandhyala]

Hi,

I'm trying to use EAP-TTLS with PAP to authenticate to an RSA server.
When the RSA server issues a user challenge to change PIN, I do not see this request, and the auth times out.
When I connect to the same server using PEAP-GTC, I get the eap_param_needed() with fld=WPA_CTRL_REQ_EAP_OTP, and txt="message from server".
Does the wpa_supplicant support inner challenges over EAP-TTLS? And, if it does, how do I detect this?

Thanks.
Shriram
