MULE –Spring Security Manager

2

Configuring the Spring Security Manager

Use Spring Security 3.0 as a Security Manager inside of Mule. You can use

any of the library’s security providers such as JAAS, LDAP, CAS (Yale

Central Authentication service), and DAO. For more information on the

elements you can configure for a Mule security manager, see Security

Manager Configuration Reference.

Example

The following example illustrates how to configure a single security provider on Mule, in this case an in-memory database of users. To configure the provider, we set up a <user-service> element and the <authentication-manager> to which Mule delegates.

Adding Spring Security ReferencesTo make Spring security work, you need to add XML schema declarations to your Mule App. Notice the above example includes the following references inside the root XML element:

xmlns:mule-ss="http://www.mulesoft.org/schema/mule/spring-security" xmlns:ss="http://www.springframework.org/schema/security" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsdhttp://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsdhttp://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsdhttp://www.mulesoft.org/schema/mule/ee/tracking http://www.mulesoft.org/schema/mule/ee/tracking/current/mule-tracking-ee.xsdhttp://www.mulesoft.org/schema/mule/spring-security http://www.mulesoft.org/schema/mule/spring-security/3.1/mule-spring-security.xsdhttp://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd

Security Filters

Security filters can be configured on an object to either authenticate inbound requests or attach credentials to outbound requests. For example, to configure an HTTP basic authorization filter on an HTTP connector, you would use the following connector security filter:

<mule-ss:http-security-filter realm="mule-realm"/>

8

When a request is received, the authentication header is read from the request and authenticated against all security providers on the Security Manager. If you only want to validate on certain providers, you can supply a comma-separated list of security provider names.

<mule-ss:http-security-filter realm="mule-realm" securityProviders="default,another"/>

This bean defines a proxy for the protected bean. When an application asks Spring for a myComponent bean, it will get this proxy instead.

<bean id="autoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="interceptorNames"> <list> <value>myComponentSecurity</value> </list> </property> <property name="beanNames"> <list> <value>myComponent</value> </list> </property> <property name='proxyTargetClass' value="true"/></bean>
