Bug
Right then Lem. Here is the latest:

Code:
roy@roy-desktop:~$ passwd -S roy
roy NP 12/15/2011 0 99999 7 -1

So the password is NOW unlocked and has been since I
Code:
cp /etc/shadow /etc/shadow.bak2

and
Code:
cp /etc/shadow.bak /etc/shadow

I presume that I can login without password because mine is the Admin account and otherwise the whole system would be inoperable?

I can confirm that there are currently NO
Code:
passwd.lock shadow.lock gshadow.lock group.lock

There may have been before the above?

NOW AFTER TAKING A BREAK

Success - I have succeeded in changing my password in root and now have access to sudo and this is how it was done!

Code:
roy@roy-desktop:~$ sudo passwd roy -S
[sudo] password for roy: 
roy P 09/10/2012 0 99999 7 -1

However, a user account is still locked.
Code:
roy@roy-desktop:~$ sudo passwd robyn -S
robyn L 12/15/2011 0 99999 7 -1
roy@roy-desktop:~$ sudo passwd robyn
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
robyn L 12/15/2011 0 99999 7 -1
roy@roy-desktop:~$ sudo passwd -u robyn
passwd: password expiry information changed.
roy@roy-desktop:~$ sudo passwd robyn -S
robyn P 09/10/2012 0 99999 7 -1

There is still a '3r' after/under 'FD'

If you can see anything else that needs to be corrected, please let me know.

Thanks very much Lem and Jim. SmilieSmilieSmilie
