Cannot manage samba48 DCs

[Andrea Venturoli]

Hello.

I've got a few Samba 4.8 DCs running in jails on 11.2 or 11.3 amd64 with 
packages I build myself with Poudriere.

I hadn't upgraded those jails in a while, but after I did, I'm having a 
problem with samba-tool:

> root at dc1:~ # samba-tool user list
> ldb: Unable to find backend for '/var/db/samba4/private/secrets.ldb' 
- do you need to set LDB_MODULES_PATH?
> Bad talloc magic value - unknown value
> Abort (core dumped)

Anyone else is experiencing this?
Is this a known issue? Any workaround? Shoud I open a bug report?

  bye & Thanks
