and the Mail Migration Task Force

what s the issue
What’s the issue ?
  • During 2003, CERN will migrate users from the legacy service ( to the new infrastructure (
  • The new service is compatible with the old one and the migration will be (almost) transparent for end users
    • The few differences that will be exposed to users are described in the next slides
  • There will be changes in USERREG
    • Compatibility is ensured, but administrators should be aware and understand the new model
background motivation
Background motivation
  • Possibility to encrypt mail sessions using secure-IMAP and secure-POP protocols
  • Mail Username/Password = NICE Username/Password
    • Single sign on across NICE, Mail and Central Web servers
  • Webmail available at
  • Shared Calendar using the Web interface (or MAPI Clients)
  • Web interface to Internet News and Public folders
  • Improved Spam Fight
  • Proposal made end of 2001
  • Pilot started beginning of 2002
  • New service approved by desktop forum October 2002
  • Userreg modification: December 2002
  • Server-side migration starts January 2003
current status
Current Status

New Server

Server-side migration

Mail User

Mail Client


Mail Server

The server is replaced,

Nothing changes for the client

changes for the users
Changes for the users
  • Nothing …
    • Same IMAP service on machine
    • No need to reconfigure Mail client
  • But …
    • Single sign on Mail / NICE (changes to userreg)
    • Pine users on linux should use at least version 4.21 and will have to type their password when pine starts (or saved locally in protected space)
    • Procmail no longer supported (workaround being investigated, users will be contacted)
changes to userreg 1
  • MAILSERV and NOVELL services will remain as today
    • Even if they will be internally mapped to one unique service, they will still appear as two distinct services in USERREG
  • NOVELL is used to create NICE accounts.
    • Same as today
  • MAILSERV is used to create mailboxes
    • Same as today
  • The creation of a mailbox for a user will force the creation of a NICE account if not already existing
    • Transparent to group administrators and users.
    • (note: today is the opposite, Creation of a NICE account forces the creation of a Mailserv mailbox if necessary)
changes to userreg 2
  • No possibility to create new mailboxes on the legacy services
    • Request for MAILBOX on MAILSERV will create a mailbox on the new service only
changes to userreg 3
  • Password change request for NOVELL (Nice) and MAILSERV will be handled identically by the Helpdesk
    • It will always change the NICE password
    • If the user has not been migrated yet, it will also change the password on the legacy Mail servers
  • Basically we will have the same login and for users not yet migrated passwords will be synchronized
  • IMPORTANT: The Listbox / Simba web interface is already authenticating users using any valid MAILSERV or NICE username/password
changes to userreg 4
  • When ?
    • December 2002
