现在做的一个程序中要求ASP.net 程序可以使用已经存在的域用户来登录(而且为了与其它程序界面一致一定要使用 Forms 登录),查找了一些相关的资料发现还是可以实现的。
主要还是依靠 advapi32.dll 中的 LogonUser API 函数。
using System.Web.Security;
using System.Runtime.InteropServices;

[DllImport("advapi32.dll", CharSet=CharSet.Auto)]
public static extern int LogonUser(String lpszUserName,
String lpszDomain,
String lpszPassword,
int dwLogonType,
int dwLogonProvider,
ref IntPtr phToken);

public const int LOGON32_LOGON_INTERACTIVE = 2;
public const int LOGON32_PROVIDER_DEFAULT = 0;

void Login_Click(Object sender, EventArgs E)

{
IntPtr token = IntPtr.Zero;

if(LogonUser(UserName.Value,
UserDomain.Value,
UserPass.Value,
LOGON32_LOGON_INTERACTIVE,
LOGON32_PROVIDER_DEFAULT,
ref token) != 0)

{
FormsAuthentication.RedirectFromLoginPage(UserName.Value,
PersistCookie.Checked);
}
else

{
lblResults.Text = "Invalid Credentials: Please try again";
}
}

其它方面的使用与普通的forms 程序没有太大的区别,也许还有更好的方法。
