for some reason one of scenario , we cane across is there are 2 Azure tenants and hence currently having users accounts like firstname.lastname@example.org and email@example.com
company wants to continue keeping services in use in 2 different tenants
however users Single sign on is problems , as in if firstname.lastname@example.org password is chnaged, it has to be manually reset by user at 2 different places.
We looked at AD connect however, thats only supported in on premise domains/forest to Azure AD tenant
is there resolve/ method for above scenarios
