With a bit of co-ordination, you can update your copy of their public key, so you can still verify incoming tokens, but would the unique id now be incorrect? Is this even a situation that can happen?</p> <p>Cheers!</p> <p>Matt</p><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=1470762" width="1" height="1">
