Please don't mess with the numbers, '10234' is still an invalid ID. You
are using the 'rid' backend and this calculates the ID from the RID
with:

ID = RID - BASE_RID + LOW_RANGE_ID

To calculate the RID from the ID, you would use:

RID = ID + BASE_RID - LOW_RANGE_ID

the 'BASE_RID' is always '0' (unless you set it) so the above becomes:

RID = 10234 - 10000

RID = 234

Please post again with the CORRECT IDs, a number cannot be that
secret ;-)
