Is it possible to configure SSO with OIDC without Well-known Configuration URL ?Issue You are trying to configure SSO in ServiceNow with OpenID Connect. But your IDP team doesn't have the Well-known Configuration URL. So, you have an impediment in creating the Identity Provider record in ServiceNow as the Well-known Configuration URL is a mandatory field.ReleaseAll Versions.CauseThe field is made mandatory in ServiceNow for a reason. We need the Well-known Configuration URL for decrypting tokens in ServiceNow and hence the Well-known Configuration URL is mandatory.In OpenID Connect (OIDC), token decryption (if encryption is used) happens using a key provided by the Relying Party (RP) — not with a key from the Identity Provider (IdP). The RP's public key is used by the IdP to encrypt the token.The RP's private key is used to decrypt it.Key used for encryption ---> RP's public keyKey used for decryption ---> RP's private keyThis public key is typically published in the RP's jwks_uri.We need the Well-known Configuration URL for fetching the keys to decrypt the tokens.Also, the OpenID Specification insists on using Well-known Configuration URL. In other words, as stated in the OIDC specification:"OpenID Providers supporting Discovery MUST make a JSON document available at the path formed by concatenating the string /.well-known/openid-configuration to the Issuer."Please refer below for the OIDC specification:https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig:~:text=OpenID%20Providers%20supporting%20Discovery%20MUST%20make%20a%20JSON%20document%20available%20at%20the%20path%20formed%20by%20concatenating%20the%20string%20/.well%2Dknown/openid%2Dconfiguration%20to%20the%20Issuer.If you do not use the .well-known/openid-configuration endpoint:The Relying Party (RP) (client application) must be manually configured with:- Authorization endpoint- Token endpoint- UserInfo endpoint- JSON Web Key Set (JWKS) URI- Supported scopes, claims, etc.This manual setup is prone to error and harder to maintain if endpoints or keys change.ResolutionAs such, ServiceNow Authentication doesn't allow configuration of SSO with OIDC without the Well-known Configuration URL.
