= OAuth 2.0 Login Sample

This guide provides instructions on setting up the sample application with SAML 2.0 Login using
Spring Security's `saml2Login()` feature.

The sample application uses Spring Boot 2.2.0.M5 and the `spring-security-saml2-service-provider`
module which is new in Spring Security 5.2.

== Goals

`saml2Login()` provides a very simple, basic, implementation of a Service Provider
that can receive a SAML 2 Response XML object via the HTTP-POST and HTTP-REDIRECT bindings
against a known SAML reference implementation by SimpleSAMLPhp.


The following features are implemented in the MVP

1. Receive and validate a SAML 2.0 Response object containing an assertion
and create a valid authentication in Spring Security
2. Send a SAML 2 AuthNRequest object to an Identity Provider
3. Provide a framework for components used in SAML 2.0 authentication that can
be swapped by configuration
4. Sample working against the SimpleSAMLPhP reference implementation

== Run the Sample

=== Start up the Sample Boot Application
```
 ./gradlew :spring-security-samples-boot-saml2login:bootRun
```

=== Open a Browser

http://localhost:8080/

You will be redirect to the SimpleSAMLPhp IDP

=== Type in your credentials

```
User: user
Password: password
