Beating my head against the wall on this- I'm trying to set up a Samba share on a RPi and for whatever reason when I try to access it from Windows I get "access is denied". When I purposely try a wrong password I get a "username or password is incorrect"- so I know it's recognizing that the password is correct, just denies access for some reason.

My testparm -s output (Trying to access Passport):

SOLVED

Steps in the end

Been breaking my head over setting up samba on my RPi2. I got my Pi last week and I set it up with no issues and then I had to reflash the SD card and start from scratch and I forgot to keep note of the steps and settings(my bad for not taking a backup, I know)

So I am facing an "Access is denied" error when trying to access from "Network" in Windows 10. I have tried with modifying group policy settings too but still the same. This is the samba.conf file :pastebin

As stated in the title, I can access the home directory, create files and folders there but as mentioned in the conf file, the other share usb is just stuck at enter password screen which I enter right every time. It just says "Access is denied."

It is a usb of ext4 format mounted at /mnt/usbd automounted at reboot.

It would be very helpful and would appreciate it if someone could guide me with what I am doing wrong.

Steps

1. I purged samba and samba-common completely and removed the conf file too.

2. Install samba and samba-common-bin and samba won't run as there's no conf file so copy smb.conf from usr/share/samba/smb.conf

3. Now this is my new share file.pastebin Changes made:
   wins support = yes
   encrypt passwords = yes
   added the share in the end as opposed to in the middle of the file from before.

4. Tested with smbtree and smbclient -L hostname

I sat up and read the samba docs for some time and started on the troubleshooting docs and tried step by step which helped me solve it. link

Thanks to everyone who tried to help me.

[EDIT] I got the SAMBA share to work. My issue was the directory I was trying to share was owned by my Paperless Docker container. I kept playing around with the permissions but nothing worked getting Windows to access this volume.

What I have done so far:

• Installed samba service on Ubuntu Server 20.04 using apt-get install samba

• Set the ownership of the directory to myUser(same as SMB user) using chown myUser:nogroup /directory

• Set permissions to everyone with chmod 770 /directory

• Created a samba user with smbpasswd -a myUser

• Added the share to the smb.conf like this:

[Folder Name]

path = /directory

read only = no

valid users = myUser

• Set the SMB protocol to:

server min protocol = SMB2

server max protocol = SMB3

(Windows is using 3.1.1)

• Restarted the Samba service with service smbd restart

After all this, I went to the windows machine, browsed the share with \\server_name\Folder Name and found it, tried to open it, and got an error saying "You do not have permission to access \\server_name\Folder Name. Contact your network administrator to request access.

I also tried mounting the shared folder via net use on the Windows machine with net use Z: \\\\server_name\Folder Name /User:myUser

The drive is mounted successfully but again, when I go to open it, I get the permission error.

I checked my windows firewall and made sure I allowed the workgroup on the samba share.

I'm not sure what else to try at this point.

The smb logs show a successful connection from the windows IP with no further detail but on the Windows side I get the permission error. Here's a portion of the logs:

At this point I don't know what else to try, and Googling and AI just keep telling me to try the same things I've already tried.

Could someone here help?
