Yes. This is from my /etc/gdm/gdm.conf (using Sarge):
And you can also change this from the gdmsetup tool by turning off secure actions menu in the Security tab

I have often wondered why exactly it defaults to requiring a password. Requiring a user who has physical access to a computer root privileges to shut it down seems fundamentally flawed to me--they could easily shut it down by removing power. However this is potentially damaging, so it seems logical to allow them to initiate a proper shutdown. Is removing this limitation a security issue for remote users? Surely disabling 'secure actions' won't allow a remote user to shutdown via gdm.. right? Anyhow, just thought I'd throw this out there to see if anyone has a good explanation. It always seemed to be a completely unncessesary and potentially frustrating default. I find it especially strange since by default any user can shut down once logged into gnome via gdm, but they become stranded once back on the welcome screen.
