OpenAM behavior Service Provider

SAML received

SAML validated

AuthN mean retrieved

SAML response sent

Class DefaultIDPAuthnContextMapper

Class DefaultIDPAdapter method: preSendResponse

Existing session verified?

AuthN level verified?

Redirect / forward

Default class return the AuthN mean corresponding to the 1st allowed context. Nothing recorded regarding other contexts.

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?

OpenAM before

AuthN contexts

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

OpenAM after SAML received

SAML validated

AuthN mean retrieved

SAML response sent

Class DefaultIDPAdapter method: initialize

Class DefaultIDPAdapter method: preAuthentication

Existing session verified?

AuthN level verified?

Redirect / forward

Class DefaultIDPAdapter method: preSingleSignOn

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

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

•  Identity Provider •  Reusability, simplify integration and increase reliability

eID: trust scheme

Service Provider

Assert Identity

Validate possession and access

OpenAM OCSP/CRLs checking

SSL mutual AuthN

No

OCSP Responder

No

OCSP down

CRLs

Yes

Cache CRL

OpenAM OCSP/CRLs mechanism no

yes

no

Cache exist?

Cache expired?

Fetch cached CRL

yes

Lookup CRL URL in X509 certificate

Lookup certificate SerialNumber in CRL

Belgian CA •  New intermediate CA issued each month with the same

CN but different SERIALNUMBER => different CRL URL

Belgian CA behavior ü  Belgian CA behavior

Ø New intermediate CA issued each month with the same CN but different SERIALNUMBER => different crl url

Ø Bulk issuing of certificates, all revoked by default Ø Big CRL can contain more than 100K entries

ü  Cache issues Ø Lot of time wasted on CRL initialization (download, validation, processing, …) Ø Storing big objects in LDAP Ø LDAP entry has CN in the name and certificateRevocationList is single valued field Ø LDAP replication can be an issue during peak time

ü  Average time for authentication is more than 10 seconds

Ø Most of the time wasted in CRL checking

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

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
