public static LdapContext getldapContextinstence() throws NamingException {
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, "ldap://192.168.1.20:636");
env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PRINCIPAL, "administrator@chenl.com env.put(Context.SECURITY_CREDENTIALS, "password"); // 密码

env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory"); // LDAP工厂类

return new InitialLdapContext(env, null);
}
这是获得连接的代码。
