Finding Administrator password
I heard that one can find the password of an ubuntu 11.10 user account by using the Guest account and then using some grep command to search out the password. I don't know the steps exactly.
Is that true?
If there is such a possibility then how it is exactly done?
What can we do against such a security problem if any?
Re: Finding Administrator password
User passwords are stored in a form where it is very unlikely that use of the grep command will be sufficient to learn the password of a user.
