[Samba] Offline Backup Error: Failed to open /usr/local/samba/private/netlogon_creds_cli.tdb

[james.atwell365 at gmail.com]

Hello,

 

Below you will find a snippet from the output of running an offline backup.
I'm specifically concerned with "Failed to open
/usr/local/samba/private/netlogon_creds_cli.tdb". is this an issue or can it
be safely ignored? I ask because the offline process appears to otherwise
run without issue. Server is Ubuntu 22.04 with Samba 4.19.2 built from
source.
