Enabling Cloud Services & Federated Authentication UPN & Email Infrastructure Changes

This document outlines the strategic plans to support evolving identity management and information security requirements at the University of Iowa. Key objectives include strengthening HawkID identity verification to meet campus authentication standards and external federation services. It discusses the change in User Principal Name (UPN) suffix from “ui” to “uiowa.edu” to ensure consistency with email addresses and facilitate federated service requirements. The document also highlights impacts on login styles, mail routing, and the implementation timeline for these changes.

  1. Enabling Cloud Services &Federated AuthenticationUPN & Email Infrastructure Changes Chris Pruess ITS AIS Directory & Authentication Services

  2. Strategic Plan Goal 3: Support evolving identity management and information security requirements. • Strategy 3: Strengthen HawkID identity verification to meet evolving campus authentication and external federation service requirements. • Roadmap: Federated Authentication and Provisioning for Cloud Service Investigations and Deployments

  3. UPN Background • What is the User Principal Name? • Internet-style login name for a user • name@domain (RFC 822) • HawkID@ui (HawkIDs in UI AD Forest) • Enforces uniqueness of IDs across the forest • Historically supported multiple-domain model • Now sets scope for “active” HawkID searches

  4. Cloud Requirements • UPN must match domain name for federated services. • eduPersonPrincipalName (eppn) is the username attribute for use in the federation • User IDs must be scoped to the institution • hawkid@uiowa.edu • UPN should match user’s email address. • hawkid@uiowa.edu

  5. 1. UPN must match domain name for federated services • Change the UPN suffix on the HawkIDfrom “ui” to “uiowa.edu” • Domain Scope: • Iowa domain is our federation domain • “ui” UPN suffix is only in the Iowa domain • ID Scope: HawkIDs; no automatic change to Service IDs • Change is mostly a back-office change

  6. UPN Change: Impact • Identify Potential Local Impact Points • Domain/Workstation/OWA Login Style • Iowa\hawkid (will continue to work) • hawkid@ui (will break) • Adopt Consistent Login: hawkid@uiowa.edu • Locally-developed application authentication • Kerberos, NTLM V2, LDAP Authentication • Shibboleth, HawkID Login Tools will manage the change

  7. 2. UPN should match user’s email address • Support mail delivery to hawkid@uiowa.edu • Common address format in higher education • Common experience with consumer services • Users sign up & login with email address • Extend our mail routing with hawkid@uiowa.edu delivery addresses • Mail alias (firstname-lastname@uiowa.edu) will continue to be supported • Initially, multiple aliases will be delivered to same (single) mailbox • Still evaluating Exchange options

  8. Projected Timeline • UPN Change • 6/9/2012 (Infrastructure Day) • Dependent on Tool and Application Updates • Mail Routing Change • August 2012 • Dependent on Mail Routing Upgrade Project • Replaces Ph with LDAP

  9. Communication Plan • CITL • AD Infrastructure Support Groups • ITS Spotlight, Help Desk • Communities • Application Developers • ITADmins • Webmasters • Researchers
