Anyone finding a problem or error within the X.500 Specifications may submit a Defect Report using the form available here.
Members of ISO/IEC JTC1/SC6 may send the Defect Report to the SC6 secretariats. In this case, please get a Defect Report number from the Project Editor (Erik Andersen).
Alternatively, put the filled Defect Report in Word format on our mailing list, and Erik Andersen will take it from there.
