Permission for Intrasite module

Hi,
I have created a Master Module using sitefinity 4.3 - Administrator->Backend Pages module.
In Masters menu i am having City Master.
I want to set permission so that certain set of users/Roles can access this City Master from backend.
How can i acheive this using Sitefinity 4.3.

Please help.
Thanks.

Is there any solution.....

I got following document for implementing permission
http://www.sitefinity.com/40/help/developers-guide/sitefinity-essentials-modules-creating-custom-modules-creating-products-module-implementing-the-data-model.html

There r number of steps. and in that there is one step where i need to set path for openaccess.
It is given that the the file is  placed in the SDK\Content\Common\Dependencies folder in the Sitefinity installation folder.
But i am not able to find this file.
Please help .. from where do i get this file?
Or give me another solution for implementing permission to intrasite module.

Please reply
Thanks.

Hello Shalaka,

This folder is part of the Sitefinity SDK that you can download from your profile on sitefinity.com. Please let me know if you need more help.

Hi,

But this solution is not as per my requirements.

And i need permission to my page.
Can u please give me solution for that.
Please refer to the image.

Hello Shalaka,

When you go to Administration -> Backend Pages and you see the list with the pages you can select Actions -> Permissions and from there you can set the permissions for the page that you created. Please note, that you didn't create a module, but rather just a page. If you want to create a custom module please refer to the documentation, for example -
