This article helps you resolve the error 530 that occurs when you browse an anonymous FTP site configured for Active Directory User Isolation in Microsoft Internet Information Services (IIS).
Original product version: Internet Information Services
Original KB number: 2649659
Symptoms
Consider the following scenario:
- You configure an FTP site in IIS.
- You allow anonymous authentication for the FTP site in the IIS manager. And then you configure Active Directory User Isolation to isolate users to their own FTP directories.
- A user tries to access the FTP site anonymously.
In this scenario, one of the following error conditions might occur:
Error condition 1: Using the ftp.exe FTP client
If the user is navigating to the FTP site using the ftp.exe command-line FTP client built into Windows or another similar command-line FTP client, the following error is displayed:
530-User cannot log in.
Win32 error: Access is denied.
Error details: Home directory lookup failed.Error condition 2: Using Internet Explorer as the FTP client
If the user is navigating to the FTP site using Internet Explorer, and the Log on anonymously checkbox is checked, selecting the Log on button will result in the user being prompted to enter the anonymous credentials repeatedly.
Cause
This behavior is by design. Configuring an FTP site for anonymous access or Active Directory User Isolation isn't supported.
Resolution
When configuring an FTP site for Active Directory User Isolation, don't allow anonymous access. FTP sites configured with Active Directory User Isolation must use Basic Authentication.
