本來主要詳細是介紹CAS和LDAP整合實現單點登錄的步驟。
1. 依《SSO之安裝CAS Server》所述安裝好CAS Server。
2. 安裝ApacheDS。安裝好ApacheDS后可以用Apache Directory Studio對其進行維護。需要注意的是ApacheDS端口號是10389,默認用戶uid=admin,ou=system,密碼secret。
3. 建立組織架構。所有人員建立在ou=people,dc=comple,dc=com下面,第一階是部門,再下面可以是職員,也可以是子部門。
4. 打開tomcat/webapps/cas/WEB-INF/deployerConfigContext.xml,找到如下內容:
<!-- | This is the authentication handler declaration that every CAS deployer will need to change before deploying CAS | into production. The default SimpleTestUsernamePasswordAuthenticationHandler authenticates UsernamePasswordCredentials | where the username equals the password. You will need to replace this with an AuthenticationHandler that implements your | local authentication strategy. You might accomplish this by coding a new such handler and declaring | edu.someschool.its.cas.MySpecialHandler here, or you might use one of the handlers provided in the adaptors modules. +--> <bean class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" />
修改成如下:
<!-- <bean class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" /> --> <bean class="org.jasig.cas.adaptors.ldap.BindLdapAuthenticationHandler"> <property name="filter" value="cn=%u" /> <property name="searchBase" value="ou=people,dc=example,dc=com" /> <property name="contextSource" ref="contextSource" /> <property name="allowMultipleAccounts" value="true" /> </bean>
還要在最后加上contextSource定義:
<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource"> <property name="userDn" value="uid=admin,ou=system" /> <property name="password" value="secret" /> <property name="pooled" value="true" /> <property name="urls"> <list> <value>ldap://192.168.12.250:10389</value> </list> </property> <property name="baseEnvironmentProperties"> <map> <entry key="java.naming.security.authentication" value="simple" /> </map> </property> </bean>
5. 將cas-server-3.5.2.1-release.zip里面的modules/cas-server-support-ldap-3.5.2.1.jar復制到cas/WEB-INF/lib。下載spring-ldap-core和spring-ldap-core-tiger到cas/WEB-INF/lib,注意對當前cas server來說,最好用1.3.2的版本。具體可以參考《Eclipse調試cas server 3.5.2.1》。
6. 重啟tomcat,登錄cas/login測試。
注意事項:
1. CAS驗證有問題時可以通過cas.log查詢一下。
2. LDAP不需要uid屬性,但一定需要userPassword屬性。
