Bug The end is in sight

Here you are Lem and thanks:

Code:
roy@roy-desktop:~$ grep roy /etc/shadow
roy::15323:0:99999:7:::

I have been duplicating your comments on a second computer and can now see the differences for myself.

I cannot explain what may have caused these errors, but I assume they can easily be corrected from root shell, or are you suggesting the use of expiredate 1 below?

Quote:
-l, --lock
Lock the password of the named account. This option disables a password by changing it
to a value which matches no possible encrypted value (it adds a ´!´ at the beginning
of the password).

Note that this does not disable the account. The user may still be able to login using
another authentication token (e.g. an SSH key). To disable the account, administrators
should use usermod --expiredate 1 (this set the account's expire date to Jan 2, 1970).

Users with a locked password are not allowed to change their password.
[...]
-u, --unlock
Unlock the password of the named account. This option re-enables a password by
changing the password back to its previous value (to the value before using the -l
option).

I certainly have read the above many times, but did not feel happy to try the -l option for passwd as I have no idea what an SSH key is. Also I did read man usermod for expiredate 1, but thought I might be opening another "can of worms"?

I can see that the end is nigh, as I will have full confidence with expert guidance and it is a great way to learn!

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
