I've never seen this use anything BUT the UID, no matter how long your
username is. That's what it has always used for me, with a two character
username, and emacsclient works fine.

Nevertheless, I tried with a username with more than 8 chars, and that
too worked fine.

How did you conclude that it was trying to use your username?

I don't suppose you have a huge UID?

Are you sure your version of emacsclient matches your version of emacs?
