如何在凭据对话框中显示域名（使用CredUIPromptForWindowsCredentials）？

Question

我使用CredUIPromptForWindowsCredentials获取用户凭据，但是如果用户像这样[或[email protected]进行登录，则凭据对话框不会显示域名。如图所示，如何在凭据对话框中显示域名？

public static NetworkCredential ShowCredDialog(string caption, string message, NetworkCredential defaultCreds = null)
{
    var credui = new CREDUI_INFO
    {

        pszMessageText = message,

    credui.cbSize = Marshal.SizeOf(credui);

    uint authPackage = 0;
    var save = false;

    CreateInAuthBuffer(defaultCreds, out var inAuthBuffer, out var inAuthSize);

    var result = CredUIPromptForWindowsCredentials(
        ref credui,

        1 /* Generic */);

    if (result != 0)
    {
        return null;
    }

    var maxUserName = 100;
    var maxDomain = 100;
    var maxPassword = 100;
    var usernameBuf = new StringBuilder(maxUserName);
    var domainBuf = new StringBuilder(maxDomain);
    var passwordBuf = new StringBuilder(maxPassword);

    var packAuthRes = CredUnPackAuthenticationBuffer(0, outCredBuffer, outCredSize,
        usernameBuf, ref maxUserName,
        domainBuf, ref maxDomain,
        passwordBuf, ref maxPassword);

    var userName = usernameBuf.ToString();
    var domain = domainBuf.ToString();
    var password = passwordBuf.ToString();

    CoTaskMemFree(outCredBuffer);

    return new NetworkCredential
    {
        UserName = userName,
        Domain = domain,
        Password = password,
    };
}
