This endpoint allows you to create, read, update, and delete trusted certificates

that are allowed to authenticate.

Deleting a certificate will not revoke auth for prior authenticated connections.
|
|
To do this, do a revoke on "login". If you don't need to revoke login immediately,
|
|
then the next renew will cause the lease to expire.
