[SOLVED] Non stop "successful auth for user" in log

[cglmicro]

Hi.

As soon as I add my PBS (version 2.1-5) as a backup storage in my 8 PVE (version 7.1-10), my /var/log/proxmox-backup/api/auth.log contains tons of this. If I disable the storage, it stop. If I limit access to certains nodes, it's slowing down, but it keep going every few seconds :

I tried rebooting the PBS and the PVE. How to troubleshoot this?

Thank you.

every pve node accesses it's storages every 10s and pbs logs 'normal' user authentactions, so this is expected for 'normal' users
to avoid this you can use tokens, when using one of those for the access to the pve storage this should not be logged anymore

Hi dcsapak.
Thanks a lot, it work like a charm with a token. I switched back to a regular user since I was always receiving an unauthorized error with a token, now it work.
