How is this possible? User-targeted file share authentication specific to Windows Server
I've been attempting to understand this issue for years, yet no one provided a clear explanation. The only insights I gained were about setting up NFS with Access-Based-Enumeration, but applying it at the folder level didn’t succeed. Before anyone responded, I confirmed I reached out to those who handled the servers, searched thoroughly, and tried every method I knew. Still, no resolution came through.
Here’s what I remember: In my area, schools use a central file server for easy access across the district. To protect against users accessing each other's files or deleting work, changes were made so only authorized people could view or modify subdirectories. The actual files remained safe, but anyone could see folder names and counts.
In the early days, students could browse other users’ folders and see usernames, yet they were restricted to their own assigned directories. When the problem became widespread, access controls were updated so each student and teacher only saw their own assigned folder—teachers had broader permissions, but still limited by view settings.
Once the issue was widely known, the authentication system was adjusted: once a user logged in, they could only access files within their designated directory. The shared network drive would appear as a dedicated network hard drive, hiding any subfolders or usernames. This meant that after mounting the share, no folder had to be selected; all files were instantly accessible at the shortcut location.
I’m puzzled because I could achieve similar results by tweaking permissions in Active Directory or assigning unique network paths for each user. But neither worked. During my recent analysis, I noticed something remarkable: even when logging into the main file server from a personal machine, only folders with matching subfolders were visible—no hidden directories appeared.
That’s surprising because, after mounting the share, I could see exactly what I would see in a district system, and I could map those shares as network drives. Any other shared folders without a single accessible folder for my username remained invisible.
This led me to focus on how the drive mapping works. On my system, I could view shared directories under my name and map them as network drives. But when entering a mapped share, I didn’t need to pick a folder with my name, nor did I see others’ folders—because the mapped directory was already rooted to my own assigned location.
This behavior applies consistently across students and staff. It stops other users’ directories from appearing or being accessed, effectively hiding them. The system ensures that only the folder linked to a specific username is visible, preventing exposure of subfolders or usernames.
My main question now is: how can I replicate this authentication approach on a standard Windows Server? I plan to set up my Windows Server 2008 R2 (the same OS as the district’s server) to handle network share access in this unique way. I won’t use Active Directory, as it won’t work for me and shouldn’t be required.
Windows server relies heavily on AD, so skipping it will cause serious issues. I’ll create an AD domain first. The version 2008r2 is no longer supported—moving to version 2019 is recommended. Set up all shares for automatic mounting; hidden shares won’t matter since users never need to access the server manually. I use a similar setup at my workplace with redirected user folders, which automatically mounts at login and gives GPOs plenty of flexibility.
NO, IT'S NOT GONE – WINDOWS 7 IS STILL FUNCTIONAL! Anything related to Windows 8, 10 or other versions needs immediate attention. Automount isn't the issue; what I encountered is far more significant and structured. I'm unsure about your setup, but it appears the end systems are all connected in a way that creates the illusion of automatic redirection. This is likely just an appearance created by AD and GPO adjustments. I don’t run a co-dependent client/server configuration like many others, and I was able to observe the behavior by connecting to their network using a personal system that isn't part of AD or affected by GPO. Seriously, can anyone clarify what has actually been implemented? I suspect root/folder authentication here ties into NFS and Access-Based Enumeration, but I’m still trying to understand how it works. I reached the limits of a folder-level lock, but I haven’t managed to access a dedicated folder under the root drive share for mounting as a root directory on a client side.
It requires no Windows 7 installations. It lacks support for many modern tools and stops receiving security patches, so auto-mounting is highly recommended. This improves the experience for everyone using it. Also, having Active Directory—even if clients aren’t connected—makes managing users and accounts much simpler. You can also mount a directory inside a shared folder on a client by simply specifying the full path. For example, to access a folder named 'bob' on a share like \\test.domain.local\share, mount \\test.domain.local/share/bob. It works perfectly in testing.
Absolutely not! Windows 7 offers greater stability and dependability than any newer version from M. The so-called "modern features" are often unnecessary and can complicate things. Regarding security updates, ESU patches are consistently applied and function correctly. Automount is useful because it lets you preview directories without fully mounting them, which is handy for testing access controls. Between servers, I only need one setup since I don’t require advanced permissions or complex configurations. The guide I reviewed simply explains ABE concepts without detailing implementation steps. You’re right—my configuration was quite advanced, so there was no need for deep UNC paths or extensive folder mounting. That was the intention of the administrators before finalizing it. At the full drive level, this is exactly how things work: the server recognizes the user’s credentials and maps the folders correctly, making the share appear as a single location even though it’s actually a restricted path. This setup avoids AD and GPOs, keeping things simple and secure.
SMB3 offers advanced capabilities like encryption, compression, and multistream support. Consider moving away from 2008r2 if possible. Newer clients will likely stop supporting it soon. Have you checked that link? It explains the process clearly. In SMB settings, you can turn on access enumeration so users only see files they’re allowed to view. This setting isn’t widely used, and most organizations automatically mount shares for access.
I appreciate the concept but don’t see a real necessity for SMB3. If I truly needed those transport features, I’d prefer Linux. Yes, I checked the link—it mainly outlines ABE’s capabilities. If I could adapt it to my needs without auto-mounting or extended UNC paths, I wouldn’t be sharing this right now. My goal is to understand how to set up a file share exactly as described. Do you know how to configure that?
It's important to upgrade to a more recent operating system, as 2008r2 has significant security concerns. I'm not sure why you prefer an older version. There are also more reliable and quicker solutions—I'll check that again. As mentioned: share a folder or volume through the Provision a Shared Folder Wizard. If you choose SMB on the Share Protocols page, the advanced settings include options to turn on access-based enumeration for the shared folder or volume (click Advanced on the SMB Settings page to view these).
