用户登录与AD域集成

### 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][Link 1]**

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

### 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

    		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
