I'm working on an SBS 2008 box which has been upgraded to Sharepoint Foundation 2010. We have a couple of computers that are "kiosk" machines and are logged in with a domain account with very limited access. This does include some read access to certain parts of the sharepoint site. However, in order to contribute, especially to issue tracking areas of the site, I want the users to login using their own domain accounts.
So, I am looking for a way to simplify the process of prompting the user for login credentials whenever they try to access a part of the web that they do not have access to. Ideally, I would like to do a custom access denied page with a login form right on the page, as if the user had already clicked the "sign in as a different user" link. I would settle for the abiliy to customize the access denied page to give the user some specific direction and maybe change the hyperlink for signing is as a different user to a more predominant button, or something of that nature.
I have Sharepoint Designer 2010 installed and I am pretty comfortable using that, but I have EXTREMELY limited code experience. So, I would need some pretty specific direction if this will require custom code to be written.
THanks in advance for any help.
