How to grant permission to use specific Application Page in SharePoint

Question

I have custom application page, now what I want to do, is to allow users ( or SPGroup ) to view and use application page. How this should be done ? Currently only administrator can view application page, other users can't.

Answer 1

I finally figure this out. The problem was that I was accessing SPSite and SPWeb objects, and users didn't have permissions to interact with this objects. So I had to wrap SPSite and SPWeb object calls into SPSecurity.RunWithElevatedPrivileges. Now everything works as exepcted.

Please make sure that you have in your codebehind

 protected override bool RequireSiteAdministrator {
    get { return false; }
  }

Then in your Init event, you can check if the current user is member of a specific group that you trust and if it's not the case, you can use the SPUtility.TransferToErrorPage("Your relevant access denied message")
