As the root user, I can change the password:
hussie:/home/claudiu# passwd
Enter new password:
Retype new password:
passwd: password updated successfully
As a non-root user I cannot:
claudiu@hussie:~$ passwd
Current Kerberos password:
passwd: User not known to the underlying authentication module
passwd: password unchanged
I also can't change another user's password from root:
hussie:/home/claudiu# passwd claudiu
Current Kerberos password:
passwd: User not known to the underlying authentication module
passwd: password unchanged
Googling the issue suggests using pwconv
and pwunconv
, but I don't have those and don't know where to find them:
claudiu@hussie:~$ pwconv
-bash: pwconv: command not found
claudiu@hussie:~$ pwunconv
-bash: pwunconv: command not found
claudiu@hussie:~$ sudo apt-get install pwconv

claudiu@hussie:~$ sudo apt-get install pwunconv

What do I do?
