Hi Carl,

I personally have used EAP-TTLS/EAP-GTC with Nokia S60 phone. Nokia S60 supplicant display EAP-GTC prompt. This prompt is set in raddb/eap.conf gtc{} subsection and defaults to "Password: " string.

EAP-GTC is thoroughly documented by RFC 3748. Typical EAP-GTC message exchange is following:

S: EAP-Request(Type=Identity)
C: EAP-Response(Type=Identity, Type-Data=<username>)
S: EAP-Request(Type=GTC, Type-Data=<prompt>)
C: EAP-Response(Type=GTC, Type-Data=<password>)
S: EAP-Success or EAP-Failure

Hello:

Are there any clients that actually display the EAP-GTC challenge?
Essentially, I am trying to use EAP-GTC similarly to how PAP Access-Challenge works:

Client: -------User/Pass---------------->Server
Client: <--Challenge Message---------Server
Client: -------Challenge Response--->Server
Client: <-------Accept------------------>Server

So far, I cannot seem to find documentation to suggest that I CANNOT do this, and the spec suggests that I can, but I cannot seem to find anything that will do this.

In addition, are there any resources that thoroughly documents EAP-GTC? The RFCs do not provide much information.
Regards.
