What is IdP and SP in SAML?

There are two actors in the SAML scenario, the Identity Provider (IdP) who “asserts” the identity of the user and the Service Provider (SP) who consumes the “assertion” and passes the identity information to the application.

Can IdP and SP the same?

A Service Provider (SP) is the entity providing the service, typically in the form of an application. An Identity Provider (IdP) is the entity providing the identities, including the ability to authenticate a user.

What is SP initiated SAML?

Service Provider (SP) initiated SSO involves the SP creating a SAML request, forwarding the user and the request to the Identity Provider (IdP), and then, once the user has authenticated, receiving a SAML response & assertion from the IdP. This flow would typically be initiated by a login button within the SP.

What is IdP initiated and SP initiated?

SP-initiated SSO could be initiated by a login button within the service provider or when the user tries to access a protected area. IdP-initiated SSO involves an authenticated user clicking a button in the Identity Provider (IdP) and being redirected to the service provider along with a SAML response and assertion.

What is SP entity ID in SAML?

An Entity ID is a globally unique name for a SAML entity, i.e., your Identity Provider (IdP) or Service Provider (SP). It is how other services identify your entity.

SAML 2.0: Technical Overview

What is endpoint in SAML?

The URLs that are used for partner-to-partner communication, such as the exchange of requests, in SAML 2.0 federations are referred to collectively as endpoint URLs . They can also be individually referred to by the name of the protocol and binding or service that they are related to.

What is a SAML payload?

SAML is XML based, which makes it extremely flexible. Two federation partners can choose to share whatever identity attributes they want in a SAML assertion (aka message) payload as long as those attributes can be represented in XML.

How does SAML IdP work?

SAML works by passing information about users, logins, and attributes between the identity provider and service providers. Each user logs in once to Single Sign On with the identify provider, and then the identify provider can pass SAML attributes to the service provider when the user attempts to access those services.

What is SP initiated SSO and IdP initiated SSO?

The most secure way to set up your integration with WorkOS is with SP-initiated SSO. This is when the user starts from your application and is sent to their Identity Provider (IdP) to log in, and then redirected back to your application. Another less secure flow is IdP-initiated SSO.

What is SP certificate?

If you are planning to use any of the advanced SAML authentication functions described in Configuring advanced functions for SAML authentication, you must create the service provider (SP) signing certificate because it is not provided out of the box. You create a new file or update the SP certificate if it has expired.

Is Active Directory an IdP?

Generally, most IdPs are Microsoft Active Directory (AD) or OpenLDAP implementations. IdPs fall into a much larger space, however, one called identity management.

What is IdP session?

An IdP session is created by default (idp. session. enabled=true) upon a successful authentication event. The IdP session uses a sliding window expiration policy that is updated under one of two conditions: An existing authentication result stored in the session is used to satisfy security demands made by an SP.

Is Okta SP or IdP?

Okta as Service Provider

The user opens Okta in a browser to sign in to their cloud or on-premises app integrations. Okta acts as the SP and delegates the user authentication to the external IdP. The external IdP authenticates the user.

Is SSO and IdP?

For the most part, SSOs and IdPs are separate. An SSO service uses an IdP to check user identity, but it does not actually store user identity.

Is Adfs an IdP?

A SAML 2.0 identity provider (IDP) can take many forms, one of which is a self-hosted Active Directory Federation Services (ADFS) server.

What is IdP issuer URI?

IdP Issuer URI: The issuer URI of the Identity Provider. This value is usually the SAML Metadata entityID of the Identity Provider EntityDescriptor . IdP Single Sign-On URL: The binding specific Identity Provider Authentication Request Protocol endpoint that receives SAML AuthN Request messages from Okta.

What is IdP metadata?

When a federated pair uses IdP metadata URL, metadata is monitored. Access monitors IdP metadata present in the system with the metadata at the URL. Metadata monitoring occurs every 24 hours. The fields such as Entity ID, Redirect SSO URL, Post SSO URL, and Signing cert pem are monitored and evaluated for changes.

What is SAML based SSO?

Security Assertion Markup Language (SAML) is an XML standard that allows secure web domains to exchange user authentication and authorization data.

What port does SAML use?

The default port number is 9444. sps.

What is IdP authentication?

An identity provider (IdP) is a system component that provides an end user or internet-connected device with a single set of login credentials that ensures the entity is who or what it says it is across multiple platforms, applications and networks.

What is the ACS URL in SAML?

The ACS URL is an endpoint on the service provider where the identity provider will redirect to with its authentication response. This endpoint should be an HTTPS endpoint because it will be used to transfer Personally Identifiable Information (PII).

What is difference between SAML and Okta?

Secure single sign-on often uses SAML as the protocol of choice, but Okta also provides several other options, including a Sign-in Widget, Auth SDK (a JavaScript-based library), Social Login, and an Authentication API for any client.

Why SAML is used for SSO?

SAML SSO is easy to use and more secure from a user perspective as they only need to remember one set of user credentials. It also provides fast and seamless access to a site as every application they access does not prompt them to enter a username and password.

Is Okta an IdP or SSO?

An identity provider (IdP) can be a cloud-based identity service like Okta, or an internal enterprise resource like Active Directory.
