We have SSO enabled in our org and have used the SSP toolkit to add our contacts into Salesforce.   Now that they're all added, I need some way to go in and enable some of them as super users so I've used the Data Loader and done an export and prepared my file with the ones I want to enable as super users .. however, when I continue with the data loader and get to the Create or Edit a map, I'm not getting SUPER USER as a field  that I can map to .. anybody got any ideas as to how I can do this.
