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

    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,

      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,
