How can I fix it? I have changed Sling refer. When I want to login my system, it redirect to the IDP login page. However, the status code is 500, I new to SAML2.0, it confused me several days. Who can help me to fix it?
Please check the below post for the solution
Apache Sling Referrer Filter:
Enable referrer filter to allow B2C tenant URL
Enable the CORS policy to allow Cross-Origin POST Request from B2C tenants.
if it doesnt' fix the issue, please enable the saml.log and see what is the issue
