Web Authentication Action in NetScaler

On one of my recent deployments, I needed to set up external access using NetScaler to an internally hosted web application (Grafana).

Grafana is a cross-platform open source application for graphical representation of data from various data sources such as InfluxDB, MySQL, PostgreeSQL, Prometheus and Graphite.

The challenge here was that the customer wanted to pre-install authentication on the NetScaler, but the users were only known to the web application itself.

The question that therefore came to me was:
How can I check the user of the web application if only the web application itself has access to the user data?

I had only used standards like LDAP, RADIUS, CERT, SAML etc. for user authentication on NetScaler, but these were not useful here because the target system should not be changed.
