CAS +LDAP实现

1.编辑CAS下的deployerConfigContext.xml，注释其中的SimpleTestUsernamePasswordAuthenticationHandler验证Handler，添加以下代码：

<property name="authenticationHandlers">
    <list>
        <bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler" p:httpClient-ref="httpClient" />
        <bean class="org.jasig.cas.adaptors.ldap.FastBindLdapAuthenticationHandler" >
            <property name="filter" value="%u" />
            <property name="contextSource" ref="contextSource" />
            <property name="ignorePartialResultException" value="yes" />
        </bean>
    </list>
</property>

<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
                <property name="pooled" value="false"/>
                <property name="url" value="ldap://172.16.5.1:389" />
                <property name="userDn" value="userDn"/>
                <property name="password" value="password"/>
                <property name="baseEnvironmentProperties">
                        <map>
                                <entry key="com.sun.jndi.ldap.connect.timeout" value="3000" />
                                <entry key="com.sun.jndi.ldap.read.timeout" value="3000" />
                                <entry key="java.naming.security.authentication" value="simple" />
                        </map>
                </property>

</bean>

2.为了支持LDAP认证方式，需拷贝以下几个jar包到cas/WEB-INF/lib/ 目录下：

cas-server-support-ldap-3.5.2.jar

spring-ldap-core-1.3.1.RELEASE.jar

spring-ldap-core-tiger-1.3.1.RELEASE.jar
