"Mickey Mouse" and D-Day

Clarification of the usual "Mickey Mouse" and D-Day story:

... a very brief United Press item, datelined London, on June 8, 1944. The exact wording in the three papers differs, thanks presumably to editing, but the substance in each is the same. Here's the UP item as it appeared in the Charleston (West Virginia) Daily Mail:

Mickey Mouse played a part in the invasion of northern France, it was revealed today.
Naval officers gathering for invasion briefing at a southern port approached the sentry at the door and furtively whispered into his ear the password of admission: "Mickey Mouse."
