X.509 curl Command in Docs

Hi,

I’m implementing X.509 client authentication on 25.0.6 and trying to understand the curl command in the docs. The following command is from the Server Administration Guide.

curl \
  -d "client_id=resource-owner" \
  -d "client_secret=40cc097b-2a57-4c17-b36a-8fdf3fc2d578" \
  -d "grant_type=password" \
  --cacert /tmp/truststore.pem \
  --cert /tmp/keystore.pem:kssecret \
  "https://localhost:8543/realms/test/protocol/openid-connect/token"

I have my Client Authenticator set to X.509. This removes the client_secret display in the Credentials tab. Where can I find the client_secret or is this a documentation error and I can leave it out?

Thanks,
Carl
