The default 6.0 installation used to come with a user 'formsadmin' that had write permission at /content/dam and was a member of forms-users, workflow-users, and contributor but this user was redundant to the permission set up for the 'dam-users' groups at the same node thus was removed before 6.1.
'fpadmin' had full permission at /content/forms/fp and was a member of 'contributors' but was removed for the same reason.
Could you please confirm, where do you see these users?
