通过java.namming包实现LDAP用户登录认证，怎么区分账号被冻结、停用、不存在等异常的业务情况呢？
参考的是：网上普遍流传的LDAP连接的代码
public boolean auth(String username, String password) {
//设置相关常量
String initialContextFactory ="com.sun.jndi.ldap.LdapCtxFactory";
String ad4ProviderURL ="ldap://ip:port";
String securityAuthentication ="simple";
String domain ="ad4";
if (!username.startsWith(domain)) {
username = domain+"\"+ username;
}
/*
* 组织参数集合
*/
Hashtable<String,String> env = new Hashtable<String,String>();
//set the initializing information of the context
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
//set the URL of ldap server
env.put(javax.naming.Context.PROVIDER_URL, ad4ProviderURL);
//set the authentication mode
env.put(javax.naming.Context.SECURITY_AUTHENTICATION, securityAuthentication);
//set user of AD
env.put(javax.naming.Context.SECURITY_PRINCIPAL, username);
//set password of user
env.put(javax.naming.Context.SECURITY_CREDENTIALS, password);
/*
* 进行LDAP连接
*/
javax.naming.ldap.LdapContext ctx = null;
//initialize the ldap context
try {
ctx = new javax.naming.ldap.InitialLdapContext(env, null);
} catch (javax.naming.NamingException ex) {
System.out.println("Authentication error, username is:"+ username);
return false;
} finally {
if (ctx != null) {
try {
ctx.close();
} catch (javax.naming.NamingException ex) {
System.out.println("Close Authentication context error");
ex.printStackTrace();
}
return true; //获取的LdapContext对象不为空，则为登录成功
}
}
return false; //否则登录失败
}
