Active Directory Structure By Erick Engelke and Bruce Campbell
People • Administered by WatIAM • Second account for elevated privileges • Elevated account is application-specific • Eg. ability to change people’s pay in DB • Use of smartcards for some people • Like passport – userids cannot be shared • Use other mechanisms to share data • Userid/password equivalent to a signature • Offer optional lower security account for use on public workstations
Groups • Very useful for managing access to data • WatIAM will manage some groups • Faculty, staff, student lists • Course lists • Delegated access to groups OU
Naming Conventions • Groups, servers, print queues need names • ECE: Electrical & Computer Engineering or Early Childhood Education • We need a shared naming convention • One of the first duties of the new committee • Will look at existing ADS and Nexus naming conventions
Workstations • subtree follows organization of university workstation management • IST manages many administration PCs • Library and residences have own IT shops • Much software purchased and policies set at faculty level • Non-windows machines also in the tree
Unix • Use AD for password authentication • Possible to use AD to store uids, gids, home directories, shells, etc. • Problem: multiple jurisdictions with distinct uid/gid and home directory systems • Various possible solutions • Use NIS or password files (but not passwords) • Virtual directories with different values for each jurisdiction
Macintoshes • Many Macs participate in Nexus already • Prefer using Apple OpenDirectory which is a virtual directory that gets userids/passwords, groups, etc. from AD • Called Magic Triangle • MacTUG group involvement on Mac related issues
Software Delivery • GPOs, Systems Center, etc. • Nexus has a wealth of software packages • Would like to move to self-serve for offices • Web based, automated delivery in future • Encourage transforms rather than new packaging
Common Applications • Software commonly needed • FireFox, Acrobat reader, Flash, etc • Set timetable for updates • Have early testers before general release
Security Considerations • Continue protective measures on DCs • Want VPN to limit access from Internet, wireless, residences, etc. • ‘reverse turing test’ like CAPTCHAs, audio, etc. - centralized people-tester – Google does this too • Certificates for user signing • Two factor authentication for some
Summary • Domain should be as simple as possible while reflecting the structure of UW • Future services like video conferencing and digital signing will make use of AD • Economize effort, minimize duplication • Take the best of ADS and Nexus
