WLAN as station bride EAP-PEAP and certificate validation

Hi guys,

I have RB set as WLAN station bridge (EAP-PEAP) to radius server.
My security profile looks like that:

EAP Methods: PEAP
TLS Mode: dont verify certificate
TLS Certificate: none
MSCHAPv2 Username: some_user
MSCHAPv2 Password: some_password

Everything is it OK and I can connect to radius server by RB WLAN, but I have one question.

How can I verify radius server certificate?
If I change TLS Mode to “verify certificate” and set TLS certificate to CA or radius server public certtificate then I can connect to WLAN.

Is it possible to verify radius server certificat in station bridge mode and EAP-PEAP?
How can I do this?
