17. OpenAM before
• AuthN contexts
• How to propose multiple AuthN means to end user?
• How to customize SSO regarding SAML AuthN context?
• AuthN level
• What if AuthN level not aligned with business requirements?
• KPIs
• How to demonstrate SLA compliance when you rely on external
systems?
• How to catch timestamps for valid sessions?

18. OpenAM before
AuthN contexts

19. OpenAM after
• Open source
• It greatly helps to understand issues when you are at the leading
edge of federation features!
• ForgeRock support
• RFE raised @ ForgeRock
• Urgent delivery of RFE as a patch
• RFE now included in new releases
• Additional hooks for custom development

21. OpenAM after after
• Additional requirements…
• Request for multiple assertions in SAML response
• Request for accessing STORK extensions in SAML requests/
responses
• … result in new RFEs
• Additional hooks
• To manipulate SAML Request objects before they are processed
• To manipulate SAML Response
• To trap and to treat SAML Response errors

22. eID Authentication: overview
Belgian electronic identity cards
•
•
Very high level of assurance: NIST 4
•
PKI based authentication mean & sturdy issuing process
•
High penetration rate among population
•
Public available infrastructure
Authentication
•
•
Confirmation of possession of and access to the card
•
Real-time validation of the status of the card

26. Belgian CA
• New intermediate CA issued each month with the same
CN but different SERIALNUMBER => different CRL URL

27. Belgian CA behavior
! Belgian CA behavior
" New intermediate CA issued each month with the same CN but different
SERIALNUMBER => different crl url
" Bulk issuing of certificates, all revoked by default
" Big CRL can contain more than 100K entries
! Cache issues
" Lot of time wasted on CRL initialization (download, validation, processing, …)
" Storing big objects in LDAP
" LDAP entry has CN in the name and certificateRevocationList is single valued field
" LDAP replication can be an issue during peak time
! Average time for authentication is more than 10 seconds
" Most of the time wasted in CRL checking

28. CRL caching implementation
• SQLite database
• Daemon that fetches CRL and creates one database per CRL
• Only storing certificate SERIALNUMBER
• Custom “Cert” module
• SQL statement to retrieve revoked certificates
• Performance
• AuthN < 100ms
• CRL checking < 5ms

29. Conclusion
• Our customers and engineers value the strengths of
ForgeRock OpenAM as an integration component in the
delivery of solutions for authentication and federation
• Adaptability
• Easy to customize components and extend functionality
• Reliability
• Scalable and stable deployments
• Agility
• Fast realizations due to open source and partnership with ForgeRock
