Error message "bad EAP size" in IPsec-Log, IKEv2-Tunnel with "eap radius"-authentification

Hello there,

I have a problem with an ipsec-configuration.

I configured an ipsec-tunnel for road warriors with “eap radius”-authentification.
If I try to establish the vpn-connection on the client I get the message “bad EAP size” in the ipsec-log on the mikrotik-router.

In the ipsec-log there is also the hint that I have to change the identity of the client in “client01”.

But how to change the ipsec-identity on a “windows 10”-client? Does anybody know that?
