I am still working on iris-for-money app: https://github.com/oliverwilms/iris-for-money
Account.csp posts a rest call with _SYSTEM username and the password.
xhttp.open("POST", "/restapi/sql/" + query, true,"_SYSTEM","SYS");
/restapi web application has Password Authentication Method enabled.
SYS is the correct password for _SYSTEM user.
I do not understand why I see login failure in Audit database.
