Administrators in NSP are not a specific User Type, administrators are Agents with special privileges giving to them by the roles they are assigned.
A special administrator User Account is defined during install of NSP. The name of this superuser is chosen in install procedure, it is normally “admin”, “sadmin”, “nspadmin”, etc. This superuser is important for setting up basic functions and for maintenance of NSP. The superuser has extended privileges, thus it is important that this user always is excluded from AD synchronization (LDAP Connections). The synchronization can result in superuser getting less privileges (and there is normally no other user having privileges to reset these setting).
