Cant recreate this in windows. Although I get this warning. Warning: File mosquitto/config/passwd_file has world readable permissions. Future versions will refuse to load this file.

The warning, which originates from MSAL for dotnet, suggests to leverage a distributed token cache.

For reference, a distributed token cache scheme may be implemented, for instance by setting up a Redis cache in Docker. A distributed cache will persist, and a cached token will not be lost on server restart.

This warning should be considered developer feedback, and is a recommendation for web apps, and not necessarily a bug or error, as discussed in the MSAL for .NET-repo. For now, the warning may be left as-is.

As a future improvement, we should consider implementing a distributed L2 cache for Flotilla.
