Please remove the double quotes in the curl commands. I was able to confirm single quotes work successfully.
I retested the curl commands as written (with double quotes) and they work. e.g.
curl “https://localhost/security/password/vault” -k -u "<administrative user name>:<password>"
Are you just saying that single quotes also work? Or that double quotes did not work for you?
