Surprise. I screwed up my FC3. Using the graphical manager for user/groups says that my /etc/shadow is not in sync with /etc/passwd. I have copied the original but now i got still strange behaviour from such programs.
As said above.
Logging in to terminal says : I have no name. There is no name for user-id 501. But i can still login with this user.
I revert the changes that i made but it's still screwed.
So far for my eperiment for a secure FC3.
Is there an solution to go back at default ? (without whole install)
