- OIDC connection
- ADP
Solution
ADP doesn’t have an auto-configuration Issuer URL (ending with ‘/.well-known/openid-configuration’), so the Auth0 UI can’t be used to create a generic OIDC connection.
It is recommended to create a Custom Social Connection to interface with the ADP authentication server. ADP also requires Mutual TLS (mTLS) support when interacting with its '/token' endpoint.
Currently, mTLSis not supported natively or in transport. Set up a proxy solution to inject the necessary certificate when interacting with ADPs ‘/token’ endpoint.
