用户登录与AD域集成[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

1.关于AD域的介绍

AD的全称是Active Directory：活动目录
域（Domain）:
1)域是Windows网络中独立运行的单位，域之间相互访问则需要建立信任关系(即Trust Relation)。信任关系是连接在域与域之间的桥梁。当一个域与其他域建立了信任关系后
2)两个域之间不但可以按需要相互进行管理，还可以跨网分配文件和打印机等设备资源，使不同的域之间实现网络资源的共享与管理，以及相互通信和数据传输
域控制器（DC）：
域控制器就是一台服务器，负责每一台联入网络的电脑和用户的验证工作。
组织单元（OU）
用户名服务器名（CN）

2.相关工具

LDAP管理工具下载

相关的安装连接步骤就不详细介绍，连接成功截图，即可获取整个集团服务器域的信息

用户登录与AD域集成[通俗易懂]

3.与shiro集成开发登录验证

3.1 全局配置

ldap.url = ldap://10.0.58.222:389/
ldap.org = ou\=\u6F4D\u6fF4\u7328\u6237,dc\=weichai,dc\=com
ldap.user = ####
ldap.password = #####
ldap.ldapfactory = com.sun.jndi.ldap.LdapCtxFactory
ldap.authentication =simple

3.2 获取AD全局配置信息

/**
 * Created by llhy n on 2019/7/21.
 * AD域参数配置
 */
public class AdConfig {
    private String url;
    private String ldapfactory;
    private String authentication;
    private String org;
    private String user;
    private String password;
    private static AdConfig adConfig = null;

    public AdConfig() {
        url = Global.getConfig("ldap.url");
        ldapfactory = Global.getConfig("ldap.ldapfactory");
        authentication = Global.getConfig("ldap.authentication");
        org = Global.getConfig("ldap.org");
        user = Global.getConfig("ldap.user");
        password = Global.getConfig("ldap.password");
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getLdapfactory() {
        return ldapfactory;
    }

    public void setLdapfactory(String ldapfactory) {
        this.ldapfactory = ldapfactory;
    }

    public String getAuthentication() {
        return authentication;
    }

    public void setAuthentication(String authentication) {
        this.authentication = authentication;
    }

    public String getOrg() {
        return org;
    }

    public void setOrg(String org) {
        this.org = org;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public static AdConfig getAdConfig() {
        if (adConfig == null){
            adConfig = new AdConfig();
        }
        return adConfig;
    }


}

3.3 shiro文件的配置

<!--AD 更改-->
	<!-- 3.1 直接配置继承了org.apache.shiro.realm.AuthorizingRealm的bean -->
	<bean id="userRealm" class="com.weichai.modules.sys.security.SystemAuthorizingRealm">
		<!-- 配置密码匹配器 -->
		<property name="credentialsMatcher" ref="credentialsMatcher"/>
	</bean>



	<!-- 凭证匹配器 -->
	<bean id="credentialsMatcher" class="com.weichai.modules.sys.security.CustomCredentialsMatcher">
	</bean>

3.5 AD域认证测试类

 * @version 2019.07.20
 */
public class AdTest {

	private static Logger logger = LoggerFactory.getLogger(AdTest.class);

	public static void main(String[] args) {
		// TODO Auto-generated method stub
        String username = "admin";
        String password = "Admin12356!!";
        openAD(username,password);
	}

	@SuppressWarnings("unchecked")
	private static void openAD(String username, String password) {
		DirContext ctx = null;
		AdConfig adf = AdConfig.getAdConfig();
		Hashtable env = new Hashtable();
		if (StringUtils.isBlank(password) || StringUtils.isBlank(username)) {
			throw new AuthenticationException("msg:用户名或者密码不正确!");
		}
		try {
			env.put(Context.PROVIDER_URL, adf.getUrl() + URLEncoder.encode(adf.getOrg(), "utf-8"));
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
		String org = adf.getOrg();
		String dc = org.replaceFirst(",dc=", "@");
		dc = dc.substring(dc.indexOf("@"));
		dc = dc.replaceFirst(",dc=", ".");

		env.put(Context.SECURITY_PRINCIPAL, username + dc);
		env.put(Context.SECURITY_CREDENTIALS, password);
		env.put(Context.INITIAL_CONTEXT_FACTORY, adf.getLdapfactory());
		env.put(Context.SECURITY_AUTHENTICATION, adf.getAuthentication());

		try {
			ctx = new InitialDirContext(env);// 初始化上下文
		} catch (javax.naming.AuthenticationException e) {
			logger.error(e.toString());
			throw new AuthenticationException("msg:AD域身份验证失败!");
		} catch (javax.naming.CommunicationException e) {
			logger.error(e.toString());
			throw new AuthenticationException("msg:AD域连接失败!");
		} catch (Exception e) {
			logger.error(e.toString());
			throw new AuthenticationException("msg:AD域身份验证未知异常!");
		} finally {
			if (null != ctx) {
				try {
					ctx.close();
					ctx = null;
				} catch (Exception e) {
					logger.error(e.toString());
				}
			}
		}
	}

}

这样就增加了域用户验证登录功能，即用户在登录时既可以使用数据库里的用户，也可以使用域服务器上的域用户和密码登录
