===== Securing WARs via {project_name} SAML Subsystem

You do not have to crack open a WAR to secure it with {project_name}.
Alternatively, you can externally secure it via the {project_name} SAML Adapter Subsystem.
While you don't have to specify KEYCLOAK-SAML as an `auth-method`, you still have to define the `security-constraints` in `web.xml`.
You do not, however, have to create a `WEB-INF/keycloak-saml.xml` file.
This metadata is instead defined within the XML in your server's `domain.xml` or `standalone.xml` subsystem configuration section.

  <subsystem xmlns="urn:jboss:domain:keycloak-saml:1.1">

        ...
      </SP>
    </secure-deployment>
  </subsystem>

----        

The `secure-deployment` `name` attribute identifies the WAR you want to secure.
Its value is the `module-name` defined in `web.xml` with `.war` appended.
The rest of the configuration uses the same XML syntax as `keycloak-saml.xml` configuration defined in <<_saml-general-config,General Adapter Config>>.

An example configuration:
