[Samba] samba upgrade fails: corrupted ./private/secrets.ldb?

[lists]

Hi,

Hope someone can help.

We're on the sernet packages, and trying to update 4.3.8 to 4.3.13 
(=latest in the repo) This is failing like this:

When looking at secrets.ldb manually:
> root at domainmember:/var/lib/samba# tdbbackup -s testMJ /var/lib/samba/private/secrets.ldb
> transaction_read: failed at off=825241399 len=24

So, perhaps I'm stuck with a corrupted secrets.ldb file..?

Any ideas how to proceed now?

Best regards,
