C# LDAP 管理
验证指定用户是否在域里认证通过：
public static bool TryAuthenticate(string userName, string password)
{
string domain = "litb-inc.com";
bool isLogin = false;
try
{
DirectoryEntry entry = new DirectoryEntry(string.Format("LDAP://{0}", domain), userName, password);
entry.RefreshCache();
DBLog.Debug("check success");
isLogin = true;
}
catch (Exception ex)
{
DBLog.Debug("域验证抛出异常 :" + ex.Message + ex.InnerException);
isLogin = false;
}
return isLogin;
}实现创建域账户的操作
