Hi,

The user can not login with their UPN's and gives an incorrect username or password error.

But they are able to logon with SAMAccountname (domain\username) format.

Thanks,

It never worked for child2 and no UPN changes

below is our scenario

Parent.com
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?
