Hi Andreas,
Thanks for your reply!
On Win7 without SAN in the user cert, authentication fails. Based on the following link SAN must be same as CN in the user cert. With this setting Win7 IKEv2 client connects to the strongswan.https://wiki.strongswan.org/projects/strongswan/wiki/Win7CertReq

Is there any way to override the EAP identity to other than CN (==SAN)?

 Hi Ajay,

from my experience Windows 7/8 does not allow you to choose the
EAP Identity when using EAP-TLS with user certificates.
If a subjectAlternativeName is present in the certificate
then this is preferred over the subjectDistinguishedName (DN).

What's new to me is that the CommonName (CN) would be chosen
as the EAP Identity.
