Previously, on remote sites in an UltimateMT setup, the Agent updater (Linux, Windows, Solaris) ruleset rejected configurations that did not contain at least one entry under Signature keys the agent will accept. This blocked saving the rule on remote sites, where signature keys are managed centrally.
This restores the Checkmk 2.4 behavior: the "at least one signature key" requirement is now skipped on remote sites in an UltimateMT setup.
