We have case study about domain, lets assume we have detail like this
We have 2 connection
Azure AD A
Azure AD B
We have 1 application and enabled 2 connection azure AD above then we disable login experience and enable identifier first,
Then login as testB@contoso.com (its suppose to be Azure AD B), what happen right now testB is register using connection AD A on user page
is that any way that we differentiate the connection even have same domain ?
