Sorted it, for anyone interested the following works for me :
Select Top 1000000 tblADusers.DisplayName, tblADusers.Displayname, tblADusers.Office, tblADGroups.Name As 'Active Directory Group Name' From tblADusers Left Join tblADMembership On tblADMembership.ChildAdObjectID = tblADusers.ADObjectID Left Join tblADGroups On tblADMembership.ParentAdObjectID = tblADGroups.ADObjectID Where tblADGroups.Name Like 'YOUR-GROUP-NAME!' Order By tblADusers.Name
If I search for a user and click on a group they're a member of, the report is produced exactly as I'd like to use but more permanently. Any way to convert the on-the-fly report? Or to expose the underlying SQL ?
