I have a small bug, if a user is not an author of a workspace, they see
double entries in the MS Calendar web part. The base location is
http://Servername/SharePoint Portal Server/applications/workspace/Calendar .

I can get to that location ok but I don't know how to change / set the
permission. I don't want to give people Author rights to workspace but I
have no problem creating a group that has limit access just to the calendar.

All suggestions appreciated on where I would set the permissions for this
web part.
