Introduction to SAML

Using SSO, you can sign in to your identity provider and access all the configured services without having to sign in to them separately. Secure Assertion Markup Language (SAML) is a protocol which is used to implement Single Sign-On (SSO). It is an XML based protocol, which the identity provider (IdP) and the service provider (SP) use to communicate.

In SAML authentication, when the user tries to sign in, the IdP authenticates the user (by verifying their credentials) and sends the authentication response to the SP. The SP, after getting the response from the IdP, provides access to the user.
