The server already prints the account, user, and remote names, isn't this sufficient?
Given unique server names on the various leafs, like leaf-abc in below example, this can be used to identify who is connecting and being marked as duplicate?

[ERR] 127.0.0.1:47744 - lid:5 - Duplicate Remote LeafNode Connection - Account:$G - user:nats-5f8nYbBl
[INF] 127.0.0.1:47744 - lid:5 - Leafnode connection closed: Duplicate Remote LeafNode Connection - Remote: leaf-abc
