Yes, i see that, how should i ask the user


Found conflict object and corresponding non-conflict object!
Delete conflict object "conflict dn"? [Y,n] -> n
Delete the non-conflict object "non-conflict dn"? [Y,n] -> y
Rename the conflict object to "non-conflict dn"? [Y,n] -> y

if --fix is set, the default would be to delete all conflict objects


Found conflict object and corresponding non-conflict object! 
Which object should be deleted?
  [1] the conflict object (dn)
  [2] the non-conflict object (dn)
  [3] none
[1, 2, 3] -> 2
Should the conflict object be renamed to 'non-conflict dn'? [Y,n] -> y

(b) is maybe a bit more user friendly, because we present them all the options 
(delete conflict or delete non-conflict) in one step not just "delete 
conflict" as in (a)
