Solved Failed to verify username!

Hey guys.

I installed the #2034 Bukkit 1.2.3-R0.1 (the beta release). But now i only get only "Failed to verify username!" error and can't connect the server. What happened there? How to fix it?

More Info: If got 1.2.3 legal edition of Minecraft, a server with the beta craftbukkit and it's finaly createt a new world (no old 1.1.* maps)

Is the error more on the server or on my computer side?

Finaly it works again. I uploaded the bukkit 1.2.3 beta but the minecraft_server.jar wasn't up to date.
New file, restart, it works. Hurrey!
