[PVE-User] Yubico doesn't work anymore

[Patrick Westenberg]

Hi everyone,

I configured PAM authentication to use yubico but I can't login anymore.

Mar  1 11:02:23 pve01 pvedaemon[4917]: authentication failure;
rhost=172.31.0.1 user=root at pam msg=Invalid response from server: 410 Gone

Is it possible, that the proxmox stuff didn't update their
implementation as Yubico deactivated deprecated ciphers and non-secured
traffic?
