administratively invalidate user's SSO session(s)

Passing on reverse engineering the ‘not really documented’ session store to
find and remove SSO sessions, but still seeking to render illicit SSO
sessions useless, is the following feasible:

When misuse is discovered that could have created illicit SSO sessions for
an account, we both flag the account in the credential store and force
password reset. Upon attempted login via the IdP with otherwise valid SSO
session in the browser we currently rely on the attribute to interrupt the
login and display an error message. Can we instead merely “force
(re-)authentication” requiring use of (newly reset) password?
