[[jax-ws-authentication]]
== Authentication

Here the simplest way to authenticate a web service user with JBossWS is
explained.

First we secure the access to the SLSB as we would do for normal (non
web service) invocations: this can be easily done through the
@RolesAllowed, @PermitAll, @DenyAll annotation. The allowed user roles
can be set with these annotations both on the bean class and on any of
its business methods.

[source,java,options="nowrap"]
----
@Stateless
@RolesAllowed("friend")
public class EndpointEJB implements EndpointInterface
{
  ...
}
----

Similarly POJO endpoints are secured the same way as we do for normal
web applications in web.xml:

[source,xml,options="nowrap"]
----
<security-constraint>
  <web-resource-collection>
    <web-resource-name>All resources</web-resource-name>
    <url-pattern>/*</url-pattern>
  </web-resource-collection>
  <auth-constraint>
    <role-name>friend</role-name>
  </auth-constraint>
</security-constraint>
 
<security-role>
  <role-name>friend</role-name>
</security-role>
----

[[specify-the-security-domain]]
=== Specify the security domain

Next, specify the security domain for this deployment. This is performed
using the `@SecurityDomain` annotation for EJB3 endpoints

[source,java,options="nowrap"]
----
@Stateless
@SecurityDomain("JBossWS")
@RolesAllowed("friend")
public class EndpointEJB implements EndpointInterface
{
  ...
}
----

or modifying the jboss-web.xml for POJO endpoints

[source,xml,options="nowrap"]
----
<jboss-web>
<security-domain>JBossWS</security-domain>
</jboss-web>
----

The security domain as well as its the authentication and authorization
mechanisms are defined differently depending on the application server
version in use.

[[use-bindingprovider-to-set-principalcredential]]
=== Use BindingProvider to set principal/credential

A web service client may use the `javax.xml.ws.BindingProvider`
interface to set the username/password combination

[source,java,options="nowrap"]
----
URL wsdlURL = new File("resources/jaxws/samples/context/WEB-INF/wsdl/TestEndpoint.wsdl").toURL();
QName qname = new QName("http://org.jboss.ws/jaxws/context", "TestEndpointService");
Service service = Service.create(wsdlURL, qname);
port = (TestEndpoint)service.getPort(TestEndpoint.class);
 
BindingProvider bp = (BindingProvider)port;
bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "kermit");
bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "thefrog");
----

[[using-http-basic-auth-for-security]]
=== Using HTTP Basic Auth for security

To enable HTTP Basic authentication you use the `@WebContext` annotation
on the bean class

[source,java,options="nowrap"]
----
@Stateless
@SecurityDomain("JBossWS")
@RolesAllowed("friend")
@WebContext(contextRoot="/my-cxt", urlPattern="/*", authMethod="BASIC", transportGuarantee="NONE", secureWSDLAccess=false)
public class EndpointEJB implements EndpointInterface
{
  ...
}
----

For POJO endpoints, we modify the _web.xml_ adding the auth-method
element:

[source,xml,options="nowrap"]
----
<login-config>
  <auth-method>BASIC</auth-method>
  <realm-name>Test Realm</realm-name>
</login-config>
----

[[jaspi-authentication]]
== JASPI Authentication

A Java Authentication SPI (JASPI) provider can be configured in WildFly
security subsystem to authenticate SOAP messages:

[source,xml,options="nowrap"]
----
<security-domain name="jaspi">
<authentication-jaspi>
<login-module-stack name="jaas-lm-stack">
<login-module code="UsersRoles" flag="required">
<module-option name="usersProperties" value="jbossws-users.properties"/>
<module-option name="rolesProperties" value="jbossws-roles.properties"/>
</login-module>
</login-module-stack>
<auth-module code="org.jboss.wsf.stack.cxf.jaspi.module.UsernameTokenServerAuthModule" login-module-stack-ref="jaas-lm-stack"/>
</authentication-jaspi>
</security-domain>
----

[IMPORTANT]

For further information on configuring security domains in WildFly,
please refer to
https://docs.jboss.org/author/display/WFLY9/Security+subsystem+configuration[here].

Here
`org.jboss.wsf.stack.cxf.jaspi.module.UsernameTokenServerAuthModule` is
the class implementing
`javax.security.auth.message.module.ServerAuthModule`, which delegates
to the proper login module to perform authentication using the
credentials from WS-Security UsernameToken in the incoming SOAP message.
Alternative implementations of `ServerAuthModule` can be implemented and
configured.

To enable JASPI authentication, the endpoint deployment needs to specify
the security domain to use; that can be done in two different ways:

* Setting the `jaspi.security.domain` property in the
`jboss-webservices.xml` descriptor

[source,xml,options="nowrap"]
----
<?xml version="1.1" encoding="UTF-8"?>
<webservices
xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="1.2"
xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee">
 
<property>
<name>jaspi.security.domain</name>
<value>jaspi</value>
</property>
 
</webservices>
----

* Referencing (through `@EndpointConfig` annotation) an endpoint config
that sets the `jaspi.security.domain` property

[source,java,options="nowrap"]
----
@EndpointConfig(configFile = "WEB-INF/jaxws-endpoint-config.xml", configName = "jaspiSecurityDomain")
public class ServiceEndpointImpl implements ServiceIface {
----

The `jaspi.security.domain` property is specified as follows in the
referenced descriptor:

[source,xml,options="nowrap"]
----
<?xml version="1.0" encoding="UTF-8"?>
<jaxws-config xmlns="urn:jboss:jbossws-jaxws-config:4.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="urn:jboss:jbossws-jaxws-config:4.0 schema/jbossws-jaxws-config_4_0.xsd">
<endpoint-config>
<config-name>jaspiSecurityDomain</config-name>
<property>
<property-name>jaspi.security.domain</property-name>
<property-value>jaspi</property-value>
</property>
</endpoint-config>
</jaxws-config>
----

[NOTE]

If the JASPI security domain is specified in both
`jboss-webservices.xml` and config file referenced by `@EndpointConfig`
annotation, the JASPI security domain specified in
`jboss-webservices.xml` will take precedence.
