An identity provider (abbreviated IdP or IDP) is a system entity that creates, maintains, and manages identity information for principals and also provides authentication services to relying applications within a federation or distributed network. [1] Identity providers offer user authentication as a service.

A SAML identity provider is a system entity that issues authentication assertions in conjunction with a single sign-on (SSO) profile of the Security Assertion Markup Language (SAML).
Alternatively, for increased security or privacy, messages may be passed by reference. For example, an identity provider may supply a reference to a SAML assertion (called an artifact) instead of transmitting the assertion directly through the user agent. Subsequently, the service provider requests the actual assertion via a back channel.
Perhaps the SP metadata is transmitted to the IdP owner via email, or maybe the IdP owner logs into a protected web app and downloads the SP metadata via a browser. Regardless of how the metadata is obtained, the result is the same: the IdP owner configures the SP metadata directly into the IdP software.

Security Assertion Markup Language (SAML) 2.0 is a version of the SAML standard for exchanging authentication and authorization identities between security domains.SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, named an Identity Provider, and a SAML consumer, named a Service ...
The profile essentially passes an SSO assertion from the identity provider to the service provider by reference (through the browser using HTTP Redirect), which is subsequently dereferenced via a back-channel exchange (i.e., the service provider "pulls" the assertion from the identity provider using SAML over SOAP over HTTP).
