Vault uses this key to install and uninstall dynamic keys in remote hosts. This

key should have sudoer privileges in remote hosts. This enables installing keys
|
|
for unprivileged usernames.

|
|
If this backend is mounted as "ssh", then the endpoint for registering shared
|
|
key is "ssh/keys/<name>". The name given here can be associated with any number
|
|
of roles via the endpoint "ssh/roles/".
