Issue Summary

The Space sidebar contains a Create page link even when the current user doesn't have the Add page permission.
If that user clicks on that link, then a No Permission page is loaded with the wrong warning message.
Even if a mail server is configured, this page won't load the Request Access button.

Environment

Fresh install of Confluence 6.12.0.
It was confirmed on 6.6.3 as well.

Steps to Reproduce

Create a fresh install of Confluence Server and do the following as the admin:

1. Add a new user (user001) to Confluence and make sure it is added only to the confluence-users group.
2. Create a new space named Space A.
   • Add the View Space Permission and remove any other related to the confluence-users group.

Access Confluence as user001:

1. Access Space A home page and you will see the Create page link in the side bar.
2. Click on the Create page link and the No Permission page is loaded with the wrong warning message.

Expected Results

1. If the user doesn't have the Add page permission, the Create page link doesn't appear in the sidebar.
2. If the link must be there, then the No permission page should give a meaningful message saying the user doesn't have permission to create pages on that Space and should render the Request Access button if the mail server is enabled.

Actual Results

1. The user has access to a Create page link even when the Add page permission is not granted.
   
2. Access the createpage.action link to a Space on which the user doesn't have the Add page permission shows a confusing message.
   • If the mail server is enabled, there's no Request Access button.
