Hi
Has this never worked or has it suddenly become a problem? Have you recently changed any users UPN's in the company?
It never worked for child2 and no UPN changes
below is our scenario

Child1.parent.com - Child1 was promoted some time ago before we implemented ADFS , both users under parent and child1 are able to logon with same UPN ie. “@abcd.com”
Child2.parent.com -Child2 was just promoted , UPN was configured same as parent and child1 but unfortunately user under Child2 cannot logon with UPN)
PS: We only have one UPN domain
Thanks,
So we are talking about 3 Active Directory domains 1 parent and 2 child domains with one UPN namespace stretched across them?
- Yes, that's right
