Add the Security Template for the profile fields

From the Sitecore core database - create a Template called SalesforceAccountLookup under:

/sitecore/templates/System/Security/SalesforceAccountLookup  

On the Builder tab of the new template, create Data section fields for each profile property that will be mapped. These will correspond with the values configured inĀ Configuring the Profile Provider Account Lookup

Using the new template created above, create a record under:

/sitecore/system/Settings/Security/Profiles/SalesforceAccountLookup 

Note the itemid GUID of this new item for the next step as it will be used for theĀ defaultProfileItemID in the configuration of the domain.
