  2. USC Enterprise Directory • Consistent data whether via Shib or LDAP • No account data released by default • Formal request for data made to Directory Steering Committee • All applications have well-defined population • Technical Details • Two Sun V440, Sun DS 5.2 with replication • active-passive with manual failover

  3. USC Shibboleth IdP • Hardware • Two Sun V240 • active-active load balancing • Authentication via Tomcat > LDAP > Kerberos • Installed Modules • HAShib (enables attribute query & Artifact profile in clustered environment) • USC Resource Handler (Status page and Logout) • USC Session Counter

  4. USC Shibboleth IdP • Simple resolver.xml (logic is in the directory) • LDAP Data Connector configured for failover • List multiple hosts for java.naming.provider.url • All ARP Rules include constraint for application specific entitlement • FERPA privacy handled via constraints

  5. Tools for Service Providers • USC specific documentation for installation and configuration • shibboleth.xml config file generator • Test Identity Provider (a la TestShib.org) • Periodic IdM & Shibboleth crash course • Local support mailing lists • Central IT officially offers “limited support”

  6. Federation Management • All documentation and configuration kept in Subversion repository • New SPs email their shibboleth.xml config file and certificate to IdP admins • Check overall sanity of configuration (/secure/) • Ensure providerID follows conventions • Comment all ARPs and metadata entries • shell script checks metadata every two weeks for expiring certificates

  7. Extending Services to Guests • All users have local LDAP entry (even guests) • Consistent data via Shib & LDAP • Allows for centralized authz management • Applications see no difference between USC members and guests • No custom code, just configuration
