Web access without login form

Hello,I have a server (s1) that valite user with electronic passport (I dont know in english that is the correct name, but I think you can make a idea).

Aslo I have a domino 8.5.3 (s2) with some aplications web that need authentication http for web user.

The idea:

Users authenticates on server s1 with electronic passport and s1 confirm to s2 the user is valid. Then s2 init session without user and password.

Can do it?, I’ve looked for information about and… I think is “imposible”, but if somebody knows, please say me something.

Thank you.
