Can your users not login with their UPN's or are you having issues with the Password Reset URL in ADFS?

Hi,

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

Thanks,

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
  
  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?
