forceAuthn/isPassive in IdPAuthExternal

[Ina Müller]

how do I configure ExternalAuthnSystemLoginHandler to tell the 
AuthenticationEngine that it supports forceAuthn or isPassive?

Is there any way to call setSupportsPassive(true) or 
setSupportsForceAuthentication(true) from my servlet configured as 
externalAuthnPath in handler.xml?
