Hi Brian,
I have the exact same problem like you.
I have tried your solution, but it does not work.
I have stripped the values like this:
String issuerStripped = issuer.Replace(", ", ",");
I also added the certificate I got from my eid card to the userCertificate
property.
I can see both are in place, but when I test it I can't login.
I get the error my certificate does not match the user credentials I
entered.
Greets,
Jeremy
