Minimum identity provider (IdP) requirements

At a minimum, your identity provider (IdP) must meet the requirements below to manage access to CDF data securely.

info

We currently only support Microsoft's Azure Active Directory (Azure AD).

The IdP must issue access tokens that the CDF API can validate. The access tokens must be a valid JWT, signed using RS256, with a public key at the location specified by the JWKS URL. Also, the IdP must have a JWKS URL that is reachable by the CDF API, and respond to requests for the JWKS end or the token endpoint within 1 second, as measured from the CDF API. Contact Cognite to have the JWKS URL added to the list of allowed JWKS URLs.

The IdP must support the following OAuth 2.0 flows:

Tokens and claims

Within a token, there are multiple claims used to assert pieces of information about a subject. Tokens issued to authenticate and authorize a subject to access CDF should contain the following claims, some of which are reserved, and the others are custom configured. See this article for more information about tokens and claims.

The table below shows the minimum required claims in a token for CDF to authenticate and authorize the subject.
