[pdm-devel] [PATCH proxmox v2 3/3] proxmox-login: add compat mode to fallback to PBS3 ticket parsing

[Christian Ebner]

The ticket info field is present for Proxmox Backup Server version 3
login response data, the client however switches to http-only in this
case.

Allow to use the old authentication workflow instead by extending the
compat mode by `Pbs3Ticket`, resulting in a full ticket instead of
the http-only one.
