xAuth v2.6.x
Authentication plugin for bukkit powered servers


About

xAuth is a second-factor authentication plugin that can be used to secure player accounts on your server. As the plugin has been enhanced over time, the direction and main purpose have expanded to new possibilities. Let's say you run a community page. With xAuth, players can authenticate using their forum accounts or using a web-driven account management system. It is also possible to get the credentials from a foreign database.

Important Notice

Before upgrading please read xAuth Documentation (external link). I have added documenation to my Confluence instance that will be updated over time. Permissions Node changed! If you get "command is restricted" you most likely did not check the release log.

Further Instructions can be found there.

Concept

The basic idea of this protection plugin is allowing players to register an account based on their player name and a supplied password and optionally their email-address. When a registered player connects to the server, that player will be prompted to authenticate his or herself by logging in. If and only if a valid password is supplied, they will regain full control of their account until their session expires.


Permissions (READ ME)

This plugin has the ability to block almost any action (including command execution) for guests and registered xauth players. It also does not use negated permissions in order to not interfere with existing plugins. Permissions are "allowed" or "restricted".

Important-Note:
In order to restrict certain actions executed by registered xauth players you need to restrict them since xauth players are trusted. This is different from guests since the default for guests is always "restrict" if not set since a guest is an unknown state. Guest nodes can also only be set via configuration and have the last say even if you might have the right to execute any command.

Please keep in mind in order to block admin commands you need to restrict them via xauth.restrict.player.command.xauth.* or add each command to a group.

This might be confusing at first but has its cons since you always can see if a permission is restricted or allowed via permission node and not via bullet point. More details can be found on page Permission-System

    @Mark615: Go

    Do you have Java 8 installed? If so use java 7.

    I am using xauth version 2.6.0 and there are some problems which i don't understand.

    no errors in the console, but when i log in with my player and try to move it, xauth tell me to log in "you must be logged in to do that". But i did before.

    I tryed to handel the problem by adding permissions to pex "xauth.allow.command.*" But why are the given perms in the plugin.yml not the permissions which i need to allow an action?

    My question is why did xauth mean that iam not logged in?

    I have found the issue regarding permission problems with xAuth 2.6.0.

    This is not a bug in xAuth. The problem is that many of you do use xAuth with Java 8 which is not recommended by me. You should use Java 7. Java 8 is still in development and the problem is related to a method i use that is not behaving in Java 8 like it does in Java 7.

    Full article is here: http://stackoverflow.com/questions/22718744/why-does-split-in-java-8-sometimes-remove-empty-strings-at-start-of-result-array

    This breaks xAuth with Java 8. So permission resolve will not work with Java 8. I will implement a fix in 2.6.1 for you so this will not happen. If you can use Java 7 or wait for my fixed version that should be compatible with java 8 split behavior.
