I just installed Ubuntu 12.10 and afterwards, I accidentally set the administrator account password to empty/null.This gave me problems when trying to do administrative tasks in the GUI, so after reading up on askubuntu I used the passwd command to set the password for the account anew.
However, at the login screen when clicking on the account, I'm not asked to enter the password; but, instead, I log in directly as if there is no password set for the account.
When doing administrative tasks in the GUI, I will be asked for a password.
What do I do to be asked for the password at login time?
I did already try, several times, in the User Account settings window to set a new password for the account. That is, in the settings window it does not say "login without a password" for my account and it shows that there is a password set for the account.
