Before You Login

Authentication on all IT Services supported Linux devices is via a newly implemented Kerberos authentication service. Kerberos manages is own list of users and passwords. We are able to populate users details into the Kerberos server but the passwords are not initially set.

If you have not changed your IT Services password since August 2013 then you must do so before you will be able to login on YARCC. All user password changes are manage via the My IT Account  web page. Click on the Password Management (IDM) link in the Manage Your Password field to change your password. You may be given the option to 'synchronise' your password, please use this if you do not want to change your password. The password change (or synchronisation) may take a few minutes before it is visible to the servers.
