Oh, when I use this command, Chad shows in the passwd file. That command for the shadow file says permission denied.
grep chad /etc/passwd
(Results:)
chad:x:1000:1000:chad,,,:/home/chad:/bin/bash
When I first log in to vsphere and select the Zentyal VM, I select the console tab. It brings up a Zentyal logo and username box. I enter the only one that works there: chad & password. It still works here. But, I cannot access the Administrator Console. Double clicking on that brings up a password box. The old admin password (chad's) doesn't work. The dialogue just goes away - not even an invalid pw error.
The User Console works, but does not appear to have enough permissions to change the password.
However, in the User Console, I used this line and had better success:
sudo grep chad /etc/shadow
Result:
[sudo] password for chad: (i entered it)
sudo: account or password is expired, reset your password and try again
changing password for chad.
(current) UNIX password: (I entered a new pw)
sudo: pam_chauthtok: Authentication token manipulation error
Sorry, try again.
[sudo].... I tried this a few times then got this error...
3 incorrect password attempts
It brought me back to a command line.
Does that provide any further info that is helpful?
