Description

I'm having a situation where I ban a player's IP (essential) but they can still access the server with a different UUID but the name is still the same.

Reproduction Steps

• Banip player
• He changes his UUID (idk how)
• Ho can connect my server after that

Expected Behaviour

I see that after fake UUID times, luckerperm will notify the console

This is clearly not a LuckPerms issue, but rather your server running in offline mode and not properly authenticating players. Such behavior is expected on an offline mode server. Consider enabling online mode in your server.properties file or follow the suggested network installation setup if you're on a network.

After installing Luckperm into the proxy, will the LP data on the backend servers be affected?

No. LuckPerms on the proxy side won't automatically sync permissions or replace LuckPerms on your backend servers.

Since you're, longer, on a network we suggest you check the Switching storage types guide on how to properly migrate your permissions and groups and you follow the Network Installation guide to sync LP data across your whole network.

Be sure to take a backup before changing your storage type and/or migrating your LP data.
