New issue by wangp on void-packages repository

https://github.com/void-linux/void-packages/issues/27565

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->

### System

* xuname:  
Void 5.4.68_1 armv7l Unknown notuptodate rdFFF
(Raspberry Pi 3B)
* package:  
samba-4.13.2_3

### Expected behavior
smbd starts normally.

### Actual behavior
smbd aborts at startup, saying it could not open secrets db. Has anybody else seen something similar on Raspberry Pi or ARM?

Log output:
```

```

Downgrading back to samba-3.6.25_14.armv7l.xbps works okay.

### Steps to reproduce the behavior

1. install samba package
2. set up /etc/samba/smb.conf
3. start the smbd service
