This preserves the actual value of the remote peer identity involved in a specific recorded IKE negotiation failure, per its description. It's the specific identity string the failing peer presented, which an admin can check against a list of authorized partners to determine whether the failure came from a known, misconfigured peer or an entirely unrecognized source attempting to connect. A failure entry showing a remote identity that doesn't match any entry in the VPN partner list would warrant treating that failure as a potential unauthorized-access attempt rather than routine misconfiguration.
