Our set up is like this:
we own our small domain, like childdomain.com. It verifies.
but childdomain.com is part of a larger organization, called 'parentdomain.com'
'parentdomain.com' has its own jira instance, as does 'childdomain.com'
but all the employees at childdomain have an emailaddress of [person]@parentdomain.com.
So here is the question: childdomain is needing to implement sso against parentdomain addresses. Can anyone advise what level we need to verify the parentdomain? The parent company already has validated it.
