CS Kerberos Passwords
Department supported linux machines and the department
Authenticated
SMTP server are using Kerberos passwords for authentication. This
password is distinct from existing Solaris and Windows passwords, as
well as from your University Directory ID.
Setting your Kerberos password for the first time
Note: if you are currently able to log into any department
supported Linux or Solaris 10 system, your kerberos password
has already been set.
If you have never set your kerberos password before, the easiest way
to set your password is to log into ringding and run
/fs/domain/bin/addkrb5pass. You will be prompted for your
current ringding or junkfood password before being
allowed to set a new Kerberos password.
If you do not have a junkfood or ringding account, or have any problems
setting your password this way, you can also visit 4120 A.V. Williams
with a photo ID and we can help you set your Kerberos password.
Changing your Kerberos password
From a kerberos-aware system (Linux, Solaris 10)
To change your existing kerberos password, log into any supported CS
UNIX system that uses kerberos (Any supported linux or Solaris 10 system),
and simply run passwd. These systems are smart enough to do the
right thing and update your kerberos password. Examples of kerberos-aware
junkfood systems are fireball and twinkie.
From other UNIX systems (Solaris 8)
If you must change your kerberos password from a solaris 8 system
(e.g., ringding, or loompa), you will need to run
/usr/local/bin/kinit and authenticate using your existing kerberos password.
Since you are doing this from a system that doesn't use kerberos for
login authentication, This is not necessarily the same as your
login password.
After successfully running kinit, run /usr/local/bin/kpasswd to set
your kerberos password. You must run kpasswd instead of
just passwd, because this system does not use kerberos for
its login authentication.
From Windows systems
There is no currently supported method of updating your kerberos password
from windows systems.
