Closed issue by Anachron on void-packages repository

https://github.com/void-linux/void-packages/issues/11570

Description:
### System

* xuname:  Void 4.19.37_1 aarch64  uptodate rFF
* package:  samba-3.6.25_14

### Expected behavior

Samba shares to be able to be mounted.

### Actual behavior
```

### Steps to reproduce the behavior

1. Install `samba`, `smbclient`
2. Setup a minimal `/etc/samba/smb.conf`
3. Create a testuser both on linux and samba (`useradd` & `smbpasswd`)
4. Try to connect locally via `smbclient -L localhost -U <username>`
5. Receive error above
