MCB SSO not requiring greater authentication methods

[Hong Ye]

Our IDP uses our in house developed webLogin for authentication which has its own session management. I set previousSession=false in MCB loginHandler that disabled Shibboleth SSO. It seems working fine. If user logged in to the SP1 that only require password, then goes to SP2 that require duo, user will be only prompted for DUO. If user goes to SP2 first, then SP1, user does not need to do any login when goes to SP1. 

Does anyone see any issue with disabling previous session in my case?

Thanks,
Hong

So if the previous allowed value matches what the user has used, then previous session handling takes place and there is never another call to the attribute resolver.

This value is then passed to the MCB as its attributeResolverID which I thought would then set the MCB authnContext to the one specified by the authContext generated value.  Currently, this does work.  It just doesn't work when doing SSO... such as when I first go to an SP that the MCB determines to only require password, then go to a second SP that the MCB determines requires two-factor, the second SP does not force the two-factor step.  Is this do-able with Shib and MCB?  We're currently using shib IDP 2.4.1.
