Username not displaying in Admin Console

I have a set of usernames like this:

950c896b22771477ee4aea99d5416899b11c08b8@race2tape.com

They are not displaying in User Summary. If I remove the @ character, then they do display? Can someone please explain why? Something to do with URLEncoder.encode?

thanks

usernames should not have an @ symbol in the name. anything after an @ symbol is supposed to be the server name. this is generally only seen in the JID which is not the same as a username. The JID is comprised of a username and a server name joined by the @ symbol (username@servername).
