Familiarize yourself with these SAML concepts.

Review the following topics to know more about SAML 2.0:

* [Typical SAML process flow (diagram)](https://www.servicenow.com/docs/fosd0LPHWKtXS5kkxIS6Uw "A typical SSO logic flow involves looking for an active session, checking user credentials, and creating the necessary token.")
* [Login (AuthnRequest) process flow](https://www.servicenow.com/docs/kTkGzgFMVbZs1KhlEW77Rw "SAML 2.0 specifies a Web Browser SSO Profile that involves exchanging information among an identity provider (IdP), a service provider (SP), and a principal (user) on a web browser.")
* [Logout (LogoutRequest) process flow](https://www.servicenow.com/docs/1WZR_4mJY5WbC9YJRuauRw "During logout, the instance issues the SAML 2.0 LogoutRequest service call to the IdP.")
* [URL information for an SSO provider](https://www.servicenow.com/docs/EEgTVQQrDoKnwZo4t6Znig "During a login challenge resulting from a URL link into the instance that requires an SSO session, the referring URL might need to be supplied to the SSO provider so that after authentication, the URL can be passed back to the instance and linked to the correct resource.")
