=== Authentication
=== Authentication and Authorization
There are two aspects to securing a web application(or context) within the Jetty server:
@ -459,3 +459,58 @@ You can then define roles that should be able to perform these protected methods
----
In the above example, only users with an `admin` role will be able to perform `DELETE` or `POST` methods.
===== Configuring Authorization with Context XML Files
While the examples above show configuration of Authorization in a `web.xml` file, they can also be configured as part of the link#link:#deployable-descriptor-file[context xml file] for a web application.
This is especially helpful if authorization needs change over time and need updated without re-packaging the whole web app.
To do this, we add a section for security constraints into the context xml file for our web app as part of the `securityHandler`.
In the example below, a `HashLoginService` is defined with authorization being granted too `foo/*` paths to users with the `admin` and `manager` roles.
[source, xml, subs="{sub-order}"]
----
<Configure id="testWebapp" class="org.eclipse.jetty.webapp.WebAppContext">
<Get name="securityHandler">
<Set name="realmName">Test Realm</Set>
<Set name="authMethod">BASIC</Set>
<Call name="addConstraintMapping">
<Arg>
<New class="org.eclipse.jetty.security.ConstraintMapping">
<Set name="pathSpec">/foo/*</Set>
<Set name="constraint">
<New class="org.eclipse.jetty.util.security.Constraint">
<Set name="name">Foo Auth</Set>
<Set name="authenticate">true</Set>
<Set name="roles">
<Array type="java.lang.String">
<Item>admin</Item>
<Item>manager</Item>
</Array>
</Set>
</New>

</Call>
<Set name="loginService">

<Set name="name">Test Realm</Set>
<Set name="config">/src/tmp/small-security-test/realm.properties</Set>
</New>
</Set>
</Get>
</Configure>
----
If roles changed in the future, administrators could easily change this context xml file without having to edit the contents of the web app at all.
==== Authentication and Authorization with Embedded Jetty
In addition to the distribution, security can be defined as part of an embedded implementation as well.
Below is an example which, like the one above, sets up a server with a `HashLoginService` and adds security constraints to restrict access based on roles.
