How is a SAML assertion validated?

The SAML Response is sent by an Identity Provider and received by a Service Provider. In the validation process is checked who sent the message (IdP EntityId), who received the SAML Response (SP EntityId) and where (SP Attribute Consume Service Endpoint) and what is the final destination (Target URL, Destination).

What is a SAML bearer token?

A SAML assertion is an XML security token issued by an identity provider and consumed by a service provider. The service provider relies on its content to identify the assertion’s subject for security-related purposes.

Can SAML and OAuth be used together?

Can you use both SAML and OAuth? Yes, you can. The Client can get a SAML assertion from the IdP and request the Authorization Server to grant access to the Resource Server. The Authorization Server can then verify the identity of the user and pass back an OAuth token in the HTTP header to access the protected resource.

Are OAuth and SAML the same?

SAML supports Single Sign-On while also supporting authorization by the Attribute Query route. OAuth is focused on authorization, even if it is frequently coerced into an authentication role, for example when using social login such as “sign in with a Facebook account”. Regardless, OAuth2 does not support SSO.

How does OAuth work with SAML?

SAML and OAuth complement each other. You can use the two protocols at the same time by letting SAML grant access to an application and using OAuth to allow access to a protected resource. You can also use an identity provider or single sign-on (SSO) service with either protocol or a combination of both.

When would you use assertion flow?

The OAuth 2.0 SAML bearer assertion flow allows you to request an OAuth access token using a SAML assertion when a client needs to use an existing trust relationship. The signature applied to the SAML assertion provides authentication of the authorized app.

Is OAuth different than SAML?

Can SAML and OAuth work together?

Systems which already use SAML for both authentication and authorisation and want to migrate to OAuth as a means of authorisation will be facing the challenge of integrating the two together. It makes sense for such systems to keep using SAML as it is already set up as an authentication mechanism.

What is an OAuth assertion?

Advertisements. Assertion is a package of information that makes sharing of identity and security information easier across various security domains. It holds the data about the subject, circumstances under which assertion is considered valid, such as where and when it can be used.

What is OAuth SAML bearer assertion flow?

What is SAML Assertion?

Does SAML bearer assertion require a refresh token?

The client isn’t required to have or store a refresh token, nor is the client secret required to be passed to the token endpoint. SAML Bearer Assertion flow is useful when fetching data from Microsoft Graph APIs (which only support delegated permissions) without prompting the user for credentials.

Does CPI SF adapter support OAuth2 SAML bearer assertion in the sfapi (soap)?

Recently (26th July 2021) our SAP Cloud Integration engineering colleagues also enhanced the CPI SF Adapter to support OAuth2 SAML Bearer Assertion in the SFAPI (SOAP). Please check the details in the handbook: Sharing with SAP community one working sample of OAuth2 + SFAPI (SOAP) with customers and partners.
