I'm currently testing the new security configuration in 1.5 RC1 and notice that when a user attempts to do something (like for a build) when they do not have the required permission the Web Dashboard displays a 'CommunicationsException' rather than a more friendly "You do not have permission to do that" message.
While the end result is that the user was correctly prevented from performing the action I can see some people thinking that there is a problem with CCNet rather than their access to it. It may be that I've missed something in the configuration but I'm not sure.
