Single Sign in Implementation

Hello, I am looking for a programmer to implement single sign on to my website. I have another website iframed in my webserver here: iframed page: [login to view URL] The actual login page is here: [login to view URL] The users of my website should be able to login with the same username/password to the iframed page as well, Ofcourse, both the username and password will be same. All I want done is that, when the login page loads, it should be automatically logged in OR the login and password should be readily filled and the user should just click on login. If you have any question, please ask me via PMB. I want this completed as soon as possible. Thanks.
