[pbs-devel] [PATCH v2 proxmox-backup 2/2] access: restrictions for editing passwords

[Oguz Bektas <o.bektas@proxmox.com>]

this endpoint isn't used anywhere yet, but it's better to make it
consistent with `update_user` password behavior.

v1:
* change this for behavior consistency in case it gets used
