Integration of products starts with SSO. In the fog of IBMs passed ignorance, we are stuck and suffer with an archaic LTPA implementation that causes more issues than good in todays trust-based IT-systems.
On the other hand, we have a fully-baked, not-integrated IAM OAUTH2 implementation for domino-db that would possibly be able to do authentication for Domino HTTP and XPages as well. Please extend this further to Sametime and Connections and in a 2nd step to support other OAuth Providers (private and public) to solve the SSO issues between the HCL Digital Solutions Portfolio once and for all.
And for those arguing about SAML - this is like OS/2 - it has lost the battle. Face the defeat.
