I'm trying to control the access to specific pages only to specific users in the community. How can i display a no access message to those users that don't have access to specific pages. Right now i have a community page with a visualforce component to but for those users without access is just a blank page. for example: 

User without access to get : "You dont have access to this page please contact support"

Hi All.

Could you please help us to find a solution for our issue?

We need to set a custom URL for our SF Community (not a Force.com site). To do that we performed the following steps:
- registered a custom domain (www.mycompany.com) using the GoDaddy service and added a necessary CNAME there to point this URL to our SF community.
- added a domain for this URL in Salesforce.
- created a Custom URL in Salesforce to point this domain to the community.

Now, if we enter a custom URL in a browser (www.mycompany.com), then it correctly redirects us to the Salesforce community. And it's exactly what we want, except one thing: in address bar of a browser we still see old URL: XXX.force.com.

So, Is it possible to configure this custom URL so that we could see "www.mycompany.com" in an address bar? What should we pay attention for to implement this behavior?

Thank you. Gennadiy.

p.s. One of our assumptions is that we should do something more with CA-certificate and SSL-certificate. If anyone knows more whether they affect on the described problem or not, please push us in a right direction.
