Fixes #60245
This PR fixes a bug where SSH host certificates are currently missing the
<hostname>.<clustername>principal, which breaks SSH access via OpenSSH and other third-party SSH clients.This PR makes sure the nodename is correctly sent in
process.firstTimeConnectIdentityRemote. Where it currently passesinstanceIdentity.ID.NodeNameit is always the empty string, identity IDs have no NodeName set when they are read from storage, the fix is to useprocess.Config.Hostnameinstead.lib/service.(*TeleportProcess).reRegisteralready does the same thing (passesprocess.Config.Hostnameinstead of theexisting identity.ID.NodeName).I also updated the logic in
lib/service.(*TeleportProcess).rotateso that existing host certificates on nodes running affected versions will be automatically repaired when the node is upgraded to a version with the fix.Changelog: fixes a bug where SSH host certificates are missing the
<hostname>.<clustername>principal, breaking SSH access via third-party clients
