Thank you so much for your suggestion. I tried it and it worked well.
However, the current SAML assertion generated has:
<saml:Issuer>http://localhost:8080/realms/crypto</saml:Issuer>
How can I do to add the format nameid-format:entity for the Issuer ? The third party application in our product needs something like this:
<saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">http://localhost:8080/realms/crypto</saml:Issuer>
Thank you so much,
Hoan
