Hi,

I have problem with 802.1X and after some time I am really desperated:

- I am writing an Embedded Ansi C client that already supports EAP-TLS, EAP-TTLS PAP and EAP-TTLS CHAP. Now I thought EAP-PEAP would not be so hard. But with the FreeRadius config I cannot get the outer TLS-tunnel running. The TLS 1.2 connection gets rejected from my SSL library "ASN parsing error, invalid input". For EAP-TLS and EAP-TTLS I have no problem with TLS 1.2 and TLS 1.3 connections.

- I tried to work with eapol_test and there is the same picture: EAP-TLS, EAP-TTLS PAP and EAP-TTLS CHAP are working, but for EAP-PEAP the outer TLS connection gets refused.

- From ChatGPT I got the info, that TLS 1.3 may cause problems to EAP-PEAP. So I have restricted the client and the FreeRadius server to TLS 1.2. No success.

Any help or idea what be very appreciated!


Best Regards,

Peter
