Suppose this mysteriously swapped order: a,b,... b,a,... Your fix increments the first list's index, so next iteration it's b,... b,a,... which is fine, but next iteration is ... a,... "a" looks new at this point, and I try to add it, but it isn't new - we just forgot that it was in "old" - and I get error 0x14 (LDAP_TYPE_OR_VALUES_EXISTS)
