Stanford Desktop Tools:  Stanford Desktop Tools Making the Move from PC-Leland to Stanford Desktop Tools Ammy Hill, IT Services Campus Readiness Specialist Jay Stamps, IT Services Desktop Systems Software Developer June 1st 2007 Tech Briefing, Turing Auditorium Moving Away From PC-Leland:  Moving Away From PC-Leland PC-Leland was created when no tool available met Stanford needs Kerberos authentication is widely used today Minimally customized standards-based open source solutions are a better alternative to home-grown software Stanford Desktop Tools Replaces needed functionality Automatically updates Essential Stanford Software Does not support Kerberos 4 Why We’re Leaving Kerberos 4 Behind:  Why We’re Leaving Kerberos 4 Behind Kerberos 4 is no longer a widely-used technology Kerberos 4 is vulnerable to offline brute force attacks that can break individual accounts As Kerberos 4 becomes a less supported technology, we risk not being able to speedily patch our infrastructure We maintain a set of Stanford-specific patches to both Kerberos 4 and Kerberos 5, which must be updated with each new release of either version of Kerberos we intend to deploy Our mixed K4 and K5 infrastructure prevents us from using many of the features of Kerberos. Improvements to Stanford Desktop Tools:  Improvements to Stanford Desktop Tools Stanford Desktop Tools for Windows version 1.3.5 was released on May 22, 2007. Features include: New version of Network Identity Manager (NIM) Simpler log in screen Login screen pops up in focus Login screen shows up in task bar when waiting for entry Support for Windows Vista Stanford Desktop Tools: Installation:  Stanford Desktop Tools: Installation Before you install, upgrade Sundial to Oracle Calendar version 10 PC-Leland will be automatically uninstalled when SDT is installed Kerberos for Windows (including Network Identity Manager) is installed and configured with SDT BigFix and Stanford OpenAFS can be installed from the Stanford Desktop Tools interface Slide6:  Slide7:  Slide8:  Slide9:  Slide10:  Slide11:  Slide12:  Slide13:  Slide14:  Slide15:  Slide16:  Slide17:  Slide18:  Slide19:  Slide20:  Slide21:  Slide22:  Slide23:  Slide24:  Slide25:  Slide26:  Slide27:  Slide28:  Slide29:  Slide30:  Slide31:  After SDT Installation is Complete:  After SDT Installation is Complete PC-Leland is replaced by Stanford Desktop Tools and Network Identity Manager Click on the S icon to access Stanford Desktop Tools Slide33:  Slide34:  Slide35:  Slide36:  Slide37:  Slide38:  Slide39:  Slide40:  Slide41:  Network Identity Manager:  Network Identity Manager NIM’s New Credentials dialog box replaces PC-Leland’s log-on screen When login is required, the New Credentials box appears. A task bar item also appears (just in case something stole focus from the login screen) Stanford Desktop Tools: Authentication:  Stanford Desktop Tools: Authentication Windows’ native Kerberos has to be supplemented The SDT installer also installs MIT Kerberos for Windows, including Network Identity Manager (NIM), and configures it for use at Stanford Right-click on the SDT system tray icon for easy access to an authentication dialog box, Kerberos ticket status information, optionally AFS tools, etc. Stanford Desktop Tools: OpenAFS:  Stanford Desktop Tools: OpenAFS If You Install OpenAFS, SDT Provides Quick Access The SDT system tray or dock icon menu lets you launch the AFS Controller or mount recently accessed AFS volumes from a list OpenAFS provides context menus for both Mac OS and Windows If you right-click or ctrl-click an AFS directory in the Mac’s Finder or in Windows Explorer, there will be an AFS menu item that you can use to view or set ACLs, etc OpenAFS, as the name suggests, is an open source project The GUI AFS Controller has been developed at Stanford We have a good working relationship with the OpenAFS project team, but can only influence, not control, the direction of future development Stanford Desktop Tools: Single Sign-on:  Stanford Desktop Tools: Single Sign-on What Is Single Sign-on? A single log-in gains you access to multiple resources, such as web applications, that require you to identify, or 'authenticate,' yourself The 2-way cross-realm trust between Stanford’s Windows Kerberos realm and the *nix-based MIT Kerberos 5 realm is now complete Some web applications (Axess, e.g.) still require a separate log-on SDT Makes Single Sign-on Easier—but… At present only two groups of users will benefit Mac users, especially those whose local account’s short name and password match their SUNet ID and password exactly Windows users whose PCs are joined to the Stanford Windows Infrastructure and who log on to their WIN account The SDT for Windows installer configures both IE and Firefox for Stanford single sign-on Go to to Test and Enable Single Sign-On Slide46:  Slide47:  Slide48:  On the Horizon:  On the Horizon Many Improvements to SDT Are Coming The ability to install and update site-licensed software that requires user authentication for download NIM will be able to change SUNet ID passwords A new user-interface for SDT in the fall More flexible, user-configurable options for scheduled or unscheduled software updating Improved, more detailed logging Moving to Stanford Desktop Tools:  Moving to Stanford Desktop Tools As of April 2008, PC-Leland and MacLeland will be obsolete Encourage the Computer Users You Support to Adopt SDT Sooner Rather Than Later When they get a new computer After a big annual deadline When other upgrades are happening SDT Is Self-Updating: To Have It Is Always to Have the Latest Version!
