- Provides a default implementation based on mappings loaded from a properties file.
- Role mappers can also be configured in the keycloak-saml susbsytem.
I use Keycloak Spring Adapter (KSA) to secure existing application. Today I realized that some functions didn't work anymore because of security checking like this:
```
GrantedAuthority adminRole = new MySpecialGrantedAuthority( "superadmin" );
for ( GrantedAuthority role : userRoles ) {
if ( role.equals( adminRole ) ) {
return true;
}
}
```
In this example, when I use KSA authorization fails.
I believe, that more preferable in `KeycloakRole` use this implementation of `equals` method.

Users who want to use PKCE support with the KeycloakInstalled adapter need to set the property
``"enable-pkce": true` in the adapter configuration / `keycloak.json`.
This adds support for the "S256" code_challenge_method to the JS Adapter.
Note that the method "plain" was deliberately left out as is not recommended
to be used in new applications.
Note that this PR includes two libraries:
- [base64-js]{@link https://github.com/beatgammit/base64-js}
- [js-sha256]{@link https://github.com/emn178/js-sha256}
`base64-js` is needed for cross-browser support for decoding the
Uint8ArrayBuffer returned by `crypto.getRandomValues` to a PKCE
compatible base64 string.
`js-sha256` library is required because the `crypto.subtle.digest`
support is not available for all browsers.
The PKCE codeVerifier is stored in the callbackStore of the JS Adapter.
Note: This PR is based on #5255 which got messed up during a rebase.
Added the metadata url as an attribute on the IDP in the keycloak saml configuration which then propagates through to the DefaultSamlDeployment where it is used on the construction of the SamlDescriptorPublicKeyLocator thereby allowing support for ADFS or other IDP which uses a path that is different to the Keycloak IDP.
To make this work when testing with ADFS a change was made to SamlDescriptorIDPKeysExtractor because it would not extract keys from metadata which contained the EntityDescriptor as the root element. The solution was to change the xpath expression in SamlDescriptorIDPKeysExtractor so that it does not require a wrapping EntitiesDescriptor but instead loads all EntityDescriptors located in the document. This allows it to handle a single EntityDescriptor or multiple descriptors wrapped in an EntitiesDescriptor in the same xpath expression. A unit test SamlDescriptorIDPKeysExtractorTest has been added which validates that keys can be loaded in both scenarios.
