Hi Paul,
Looking at the username from cert is an excellent idea. I haven't
thought of it myself. I though of using a lookup table from cert subject
name to Linux username like libpam-pkcs11 does, but I didn't know how to
code it for I am newbie in PAM.
I will wait some time until I sleep over it. Maybe I see some new
solution in my spirit. Lord willing.

I can publish a patch diff. I have really made very small

I would also want to map certificate subject lines to unix usernames,
put the user into utmp and display the connected user with `w`
or `who` commands. But I'm not sure how it's done yet.
Attached is what I had gobbled together to pull IDs from certificates
inside pam_url for IKEv2.
Maybe I should think of forking pam_url and supplying a Debian .deb
package, since only .rpm exists in the wild?
I don't think it is well maintained or active upstream?
pam-authenticate is a very practical method of access control. I
would like to clear the doubts that it decreased the security of
IKEv2 VPN, and that it is unprofessional, because pam_url calls a
cgi-bin script in .php over a TLSv1.3 connection.
It still beats 10 round trips of EAPTLS on Windows :)
