  9. LDAP / NDS • campus network is Novell • we are installing an NDS ‘tree’ • everything / everyone in the tree • can be queried using LDAP • meets BUILDER’s needs

  10. LDAP / NDS • Infrastructure Issues • security • reliability • needs confidence

  11. LDAP / NDS • installation issues • NT perl versions and DLL libraries • test system blues • no go without SSL • reliant on completion of tree • eg: no access in medical school

  12. LDAP / NDS • Where are we TODAY? • proved the technology works • NT / Perl / Libraries • test system in place • developing the web front end • confidence testing • 20 person days so far • still a long way to go

  13. Talis • library system is BLCMP Talis • BUILDER developing toolbox • all key members of institution pre-registered with Talis • authentication tool ‘fell out’! • meets BUILDER’s needs

  14. Talis • infrastructure issues • none • installation issues • none that had not been previously solved by other toolbox functions • errors in Talis data appearing

  15. Talis • Where are we TODAY? • authentication is in use • electronic short loan • exam paper database (shortly) • test use by other bham web site • developing BUILDER string • 4 person days so far
