New Users / Account Renewal
1. Obtaining a New User Account
2. Renewing your Visitor ID and Kerberos principle
3. Changing your Kerberos password
Kerberos authentication is required in order to access
the Lattice QCD computing facilities at Fermilab. For remote users, the
following are required:
- Fermilab Visitor ID
- Fermilab Kerberos Principal
- Unix accounts on the LQCD cluster machines
Step 1. Fermilab Visitor ID and Kerberos Principal
If you have previously used computers at Fermilab, you
may already have a Visitor ID. Use the Fermilab telephone directory
search pages to look for your name. If an entry exists for you and that entry lists
a Visitor ID number, record that number for filling out the application
form. The details regarding the Visitor ID application process for a
Non-Employee Off-Site Fermilab User can be found at this link
(please see the section for Off-site Visitors).
If you never had a Fermilab Visitor ID then you will
need to submit the online application form for
a Visitor ID and Kerberos principal using this
link.
In the pulldown menu under "Provide your affiliation", select "Lattice QCD". Important - For Fermilab contact name, please list 'Paul Mackenzie'.
For Fermilab contact phone, please list 'x3347'.
And for Fermilab contact email, please list 'mackenzie@fnal.gov'
If you have requested or wish to request a CRYPTOCard please go to this link
and fill the "Request for Crypto Card" form. We can ship your
CRYPTOCard to you. What is a Cryptocard?
Step 2. Unix accounts on the
LQCD cluster machines
After you have received email with information about your
Kerberos principal and CRYPTOCard (if you requested for one), send email
to lqcd-admin@fnal.gov
to request an account on the LQCD clusters. In the email mention
your kerberos principal, identify your project
affiliation using the current year allocation table listed here
and provide us with your mailing address where we can send your
CRYPTOCard to (if you requested for one).
Your Fermilab ID and
computer privileges expire at different intervals depending on your
classification (employee, contractor, on-site or off-site visitor). If
you have received an email from the Fermilab Service Desk about a soon
to expire or expired Fermilab Visitor ID and computer privileges
then follow the two steps listed below to renew your VID and Kerberos
principle. Please note that even when your ID and computer privileges
expire we do not erase any user data stored on the Fermilab LQCD
clusters.
In case you need to find your VID number then use the Fermilab
telephone directory
search pages to look for your name. If an entry exists for you and that entry lists
a Visitor ID number, record that number for filling out the application
Step 1.
Re-read the Fermilab Policy on Computing.
Step 2. Fill out this
form to renew your Visitor ID.
In the pulldown menu under "Provide your affiliation", select "Lattice QCD". Important - For Fermilab contact name, please list 'Paul Mackenzie'.
For Fermilab contact phone, please list 'x3347'.
And for Fermilab contact email, please list 'mackenzie@fnal.gov'
If you still need further assistance please email us at lqcd-admin@fnal.gov
A month before your Kerberos password is set to expire you will receive a reminder email
from the Fermilab Service Desk requesting you to change your password as soon as you can.
Please do not ignore this reminder email and act upon it as soon as possible since you
will lose remote login privileges to the USQCD cluster resources at Fermilab once your
Kerberos password has expired.
Follow the instructions for changing your Kerberos password as listed in the
"Strong Authentication at Fermilab" manual section 3.3
"Changing your Kerberos Password".
Additional notes to pay attention to are appended below:
- If you don't have an appropriate machine on which to change your password,
find someone who does, and borrow his or her command prompt.
- Do not use a telnet session with cryptocard authentication to change your
password. Telnet with cryptocard authentication uses a clear text session
so any password sent can be easily viewed by someone using network sniffer
software. If you must run the
kpasswd command on a remote system, use an
SSH client with cryptocard authentication.
- If you are using WRQ Reflection under Windows, you can use the WRQ
Kerberos Manager application to change your Kerberos password. You can
find this application by following Start->Programs->Reflection->Utilities.
Once you start the Kerberos Manager, select the Change Password option
in the Tools menu.
- If you are using MIT's Kerberos for Windows (KfW) version 2.5 or better
(tested 2.6 beta 9), you can use the Leash32 client to change your
password.
- If you are using MIT Kerberos for Windows (KfW) version 3.0 or better with
Network Identity Manager (NetIdMgr) and have configured your FNAL.GOV
identity in NetIdMgr, you can use NetIdMgr to change your password.
- If your password expires before you change it, you can still change it as
long as you remember what it is. If you don't remember it, you can have it
reset by contacting the Service Desk at 630-840-2345
- Your CRYPTOCARD will stop working when your kerberos password expires. It
will start working again once your password is changed and valid.
