add primary user to report

Hi,

I am having an issue with getting the correct join that would bring in the 'Primary User'. Can someone tell me which join needs to be added to the following report?

SELECT    COALESCE(os.[Name],ci.[Name]) [Computer Name]
        , ra.[CreatedDate] [Retired Date]   
        , cs.[Model]
        , cs.[Manufacturer]
        , cs.[Identifying Number] [Serial Number]   
        , os.[OS Name]
        , os.[OS Revision]  
        , vi.[Name] [Location]
            
FROM [vRM_Computer] c
INNER JOIN [vRM_Computer_Item] ci
    ON c.[Guid] = ci.[Guid]
INNER JOIN ResourceAssociation ra
   ON ra.ParentResourceGuid = c.Guid AND ra.ResourceAssociationTypeGuid = '3028166F-C0D6-41D8-9CB7-F64852E0FD01'
   AND ra.ChildResourceGuid = '492C463B-AFA2-4DD6-AE73-6FD2C7B0E489'
LEFT OUTER JOIN ResourceAssociation loc
    ON loc.ParentResourceGuid = c.Guid AND loc.ResourceAssociationTypeGuid = '05DE450F-39EA-4AAE-8C5F-77817889C27C'
LEFT OUTER JOIN vItem vi
    ON loc.ChildResourceGuid = vi.Guid
LEFT OUTER JOIN vHWProcessor p
    ON c.Guid = p._ResourceGuid
LEFT OUTER JOIN vHWComputerSystem cs
    ON c.Guid = cs._ResourceGuid
LEFT JOIN    [Inv_AeX_AC_Identification] os
    ON os.[_ResourceGuid] = ci.[Guid]

ORDER BY  ra.[CreatedDate]
