It's cane or beet sugar that causes the cidery taste. Corn sugar is fine for priming.
In fact, a lot of beer recipes call for pounds of corn sugar along with various extracts in the brewing process. They wouldn't do that if there was a big problem with it. Of course there are better substitutes than corn sugar for your fermentables.
