Okay. Out of curiosity, why not?

I'd like to try this, but for some reason, I can't get a new user going.
I create the user like this:

[root at localhost ~]# adduser -ppassword -m roger

But when I try to log in at the GUI prompt to get into Gnome, it always
password incorrect. Am I creating the user wrong?
