All imported users will be by default assigned to DotNetNuke roles defined as "Auto" (default setting is Registered Users and Subscribers).
Role mapping has two options:
Mapped Role Field - mapping users to roles defined in transaction table (Select column containing User Role).
Master Sync Role - users will be assigned to selected role.
Additional option is "Locked Sync Role" - it allows exclusion of users belonging to selected role from export to external database.
By default no Super Users will be exported.
