Limiting requests based on keycloak username problem

[averevki]

Since 2024-12-17 nightly kuadrant-operator-catalog image, we have our test that should limit requests based on the keycloak user username failing. It doesn't limit requests for users anymore. Setup is similar with one of the kuadrant user-guides but without the kubernetes identity. Can you please help me to understand what's wrong with ours?

There could have been a change in structure we are not aware of, but I didn't find any new commits around this date. I did some research, and from docs it seems like the RLP counter value might be something different. Something like metadata.filter_metadata.envoy\.filters\.http\.ext_authz.identity.user to fetch dynamic metadata, but I wasn't been able to make limitador parse this value.

Also, for the future debugging, is there a method to check what dynamic metadata is actually parsed? Thank you
