How to define PreviousSession as authentication method in shibboleth idp4

[iljkr at tiscali.it]

  Hi,
I'm migrating from shibboleth idp2 to idp4.

In my idp2 conf, I
have this handler configured:


urn:oasis:names:tc:SAML:2.0:ac:classes:PreviousSession

(source:
https://shibboleth.atlassian.net/wiki/spaces/SHIB2/pages/2577072310/IdPAuthPreviousSession)

We
have an External login flow.
Whithout this handler the idp does not do
SSO, and when the SP changes, the user is required to
re-authenticate.

The problem is that i can't replicate this
configuration on the idp4. It appears to have been deprecated.

How can
I get the same result as my old setup on idp2 and have SSO working on
idp4 as well?

Thank you,
CP
