Not allowed to access middleware from another namespace

[ilanKushnir]

What is the best practice for using traefik-forward-auth across multiple namespaces?

• should I deploy it in a single namespace and change providers.kubernetesCRD.allowCrossNamespace to true? - if so, how can I do it?
• should I deploy it in each namespace separately?
• is there any other solutions? I planned to deploy it in my security namespace but couldn't access the middleware from other namespaces.

thanks!
