| All CSG-maintained systems in the Department use the [[http://web.mit.edu/Kerberos/|Kerberos]] network authentication infrastructure deployed by the Department and the central College computing services, [[http://www.ict.imperial.ac.uk|ICT]], that allows you to use the same passphrase to access all standard university services, such as email, remote login and web services. | We are aiming towards a single College password for each user, that allows you to access all standard university and Departmental services, such as email, remote login and web services. Currently, all CSG-maintained Linux systems in the Department will accept your College password (actually a [[http://web.mit.edu/Kerberos/|Kerberos]] password stored in the College Active Directory domain), or your DoC linux (Kerberos) password if you have one. DoC Windows machines currently use their own Windows-specific passwords, but will hopefully accept College passwords by the end of summer 2009. |

Authentication Services
We are aiming towards a single College password for each user, that allows you to access all standard university and Departmental services, such as email, remote login and web services. Currently, all CSG-maintained Linux systems in the Department will accept your College password (actually a Kerberos password stored in the College Active Directory domain), or your DoC linux (Kerberos) password if you have one. DoC Windows machines currently use their own Windows-specific passwords, but will hopefully accept College passwords by the end of summer 2009.
Kerberos also enables the ability to use ticket-based automatic single sign-on across services that have been extended to support it. Departmental services that support ticket-based authentication include:
- Remote login via Secure Shell (SSH);
- Departmental web pages accessed over HTTPS from Kerberos-aware browsers like Firefox;
- Network filesystem access via Windows Networking (SMB/CIFS) - but using your DoC Windows AD/Kerberos ticket.
When you login to (or unlock a locked session on) a DoC Linux machine, you receive a Kerberos ticket that lasts 8 hours. All the above services should then work without asking you for your password again.
