Is your feature request related to a problem?

We're missing the EAP-TTLS + PAP, as it's clearly stated in esp_wpa2.h that

@attention 2. wpa2 enterprise authentication can only support TLS, PEAP-MSCHAPv2 and TTLS-MSCHAPv2 method.

A lot of corporate/student networks support/require PAP.

Describe the solution you'd like

Support PAP as PHASE2 like it is offered in the esp_eap_ttls_phase2_types ENUM:

typedef enum {
    ESP_EAP_TTLS_PHASE2_EAP,
    ESP_EAP_TTLS_PHASE2_MSCHAPV2,
    ESP_EAP_TTLS_PHASE2_MSCHAP,
    ESP_EAP_TTLS_PHASE2_PAP,
    ESP_EAP_TTLS_PHASE2_CHAP
} esp_eap_ttls_phase2_types ;

Describe alternatives you've considered

None, we need PAP.

Will #6398 resolve the issue?

Hello @hgshoggins, any chance you take a look on mentioned PR above?

[hgshoggins]

I'd love to, but actually I'm not sure how I can manage to do so. Ideally, I would work directly from published upstream master. Unless you guide me on how to work from that PR, but that's out of the scope of these comments, and I'm afraid I don't have time/skills for that.

Clearly, here is what is at stake right now: I have a WiFi network to which I connect machines (Linux + Windows + Android) authenticating to a RADIUS server through EAP-TTLS (PAP for Phase2), and I can see it's not working with my ESP32, but that's all I can debug (as well as the RADIUS server's debug log saying the ESP32 is refusing the EAP type). And noting that, the comment in the code saying that only TLS, PEAP-MSCHAPv2 and TTLS-MSCHAPv2 methods are supported pointed me here in the Issues section. But I might not be your best chance to debug further.

I hope someone else can.

Thanks for your fast answer @hgshoggins, to validate your issue you can just download version 2.0.3-RC1 we released yesterday and it includes mentioned PR.

To do so, you need to change link in Arduino IDE settings to development release link, take a look here on installing guide.

If there is something unclear, don't hesitate to ask :)
