我已经使用C#为IIS FTP 8创建了自定义身份验证器。我已正确设置自定义功能的处理器,这样IIS使用我的DLL,但是当我尝试登录我总是得到:IIS FTP 8自定义身份验证授权规则拒绝访问
Response: 331 Password required
Command: PASS ********
Response: 530-User cannot log in, home directory inaccessible.
Response: Win32 error: No such interface supported
Response: Error details: Authorization rules denied the access.
Response: 530 End
我敢肯定,我已经排除了文件夹的权限 - 这是敞开的因为它可以。所以,据我了解的信息 - 它告诉我,我没有任何授权规则。但似乎没有办法为自定义身份验证器添加一个。 IIS管理器中的用户界面屏蔽了常规设置功能,因此您无法在其中添加任何设置。
我试过应用CMD:
appcmd.exe set config "mysite" -section:system.ftpServer/security/authorization /+"[accessType='Allow',roles='administrators',permissions='Read, Write']" /commit:apphost
与作用(客人,*等)没有成功的变化。
我试图编辑在的applicationHost.config网站的入口,但我找不到在哪里把它放在其他比这个“非定制”的例子来自微软的文档的任何文件:
<location path="ftp.example.com">
<system.ftpServer>
<security>
<authorization>
<add accessType="Allow" roles="administrators" permissions="Read, Write" />
</authorization>
当我在我的配置中的指定位置添加授权标签,FTP服务将不会重新启动。
那么,当您使用自定义FTP身份验证提供程序时,您如何添加授权规则?
为了完整起见,以下是提供者类的代码。请注意输出到LogMessage方法中的文本文件。这就告诉我,一切正常 - 它不能到达用户的主文件夹,因为它没有授权规则。
using System;
using System.IO;
using Microsoft.Web.FtpServer;
namespace MyCustomFtpExtension
{
public class DatabaseAuthenticator : BaseProvider,
IFtpAuthenticationProvider,
IFtpRoleProvider, IFtpHomeDirectoryProvider, IFtpPostprocessProvider,

public bool AuthenticateUser(string sessionId, string siteName, string userName, string userPassword,
out string canonicalUserName)
{
canonicalUserName = userName;
var result = DatabaseHelper.Authenticate(userName, userPassword);
if (result)
{
LogMessage("Login Success: " + userName); //this message appears
}
else
{
LogMessage("Login Failure: " + userName);
}
return result;
}
string IFtpHomeDirectoryProvider.GetUserHomeDirectoryData(

{
return true; // I don't care about this - if they authenticate, that's all I need.
}
//to keep the sample short I took out the log provider - it was copy/paste from Microsoft's example
//this is a quick and dirty output so I can see what's going on (which isn't much)
private void LogMessage(string logEntry)
{
using (var sw = new StreamWriter(_logfile, true))
{
// Retrieve the current date and time for the log entry.
var dt = DateTime.Now;
sw.WriteLine("{0}\t{1}\tMESSAGE:{2}",
dt.ToShortDateString(),
dt.ToLongTimeString(),
logEntry);
sw.Flush();
}
}
}
