Samba не может добавить запись пользователя, как мне это исправить?

Я настраивал Samba и пытался добавить пользователя домена, но он возвращает это:

failed to add entry for the user student

Это команды, которые я сделал до сих пор:

frigate@frigate-desktop:~$ su 
Password: 
root@frigate-desktop:/home/frigate# nano /etc/samba/smb.conf 
root@frigate-desktop:/home/frigate# groupadd -g 201 machines
root@frigate-desktop:/home/frigate# mkdir -m 0775 /home/ntlogon
root@frigate-desktop:/home/frigate# mkdir /home/samba /home/samba/profiles
root@frigate-desktop:/home/frigate# chmod 1755 /home/samba/profiles/
root@frigate-desktop:/home/frigate# useradd -m test
root@frigate-desktop:/home/frigate# passwd test
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
root@frigate-desktop:/home/frigate# smbpasswd -a test
New SMB password:
Retype new SMB password:
Added user test.
root@frigate-desktop:/home/frigate# smbpasswd -a root
New SMB password:
Retype new SMB password:
Added user root.
root@frigate-desktop:/home/frigate# smbpasswd -a student
New SMB password:
Retype new SMB password:
Failed to add entry for user student.
root@frigate-desktop:/home/frigate# smbpasswd -a student
New SMB password:
Retype new SMB password:
Failed to add entry for user student.
root@frigate-desktop:/home/frigate# smbpasswd -a stu
New SMB password:
Retype new SMB password:
Mismatch - password unchanged.
Unable to get new password.
root@frigate-desktop:/home/frigate# smbpasswd -a stu
New SMB password:
Retype new SMB password:
Failed to add entry for user stu.

Как я могу добавить этого пользователя в Samba?
