I get this error when I try to authenticate using Gnome GUI. I have NO authentication problem when I use terminal. It is suggested here that I need to do
sudo chown -R myusername:myusername /home/myusername
However this leads to another error
chown: cannot access `/home/myusername/.gvfs': Permission denied
And this happens even if I run the above command as root. I read in launchpad that .gfvs is a FUSE mount point so it can not be manipulated by root. However still have no clue how to fix this.
Appreciate your help.
