Apply LDAP update files in blocks of 10, as originally designed.
    
    In order to have control over the order that updates are applied
    a numbering system was created for the update files. These values
    were not actually used.
    
    The updates were sorted by DN length and in most cases this was
    adequate for proper function. The exception was with roles where
    in some cases a role was added as a member of a permission before
    the role itself was added so the memberOf value was never created.
    
    Now updates are computed and applied in blocks of 10.
