I am trying 3rd party authentication in my web application.
I am trying to use Google, Yahoo, AOL authentication providers. These authentication processes I am using to authenticate my application. I've done authentication for GMAIL.
In this authentication I've done following steps
1.Registered in GMAIL and mentioned destination page for remote authentication.
2.Used URL of Gmail authentication in my code and redirected to it
3.After entering correct credentials I retrieve TOKEN
4.Extract this TOKEN in destination page which I've mentioned in 1st step and with that Token I am calling Web service of GMAIL and retrieve User Details form it and showing on that page.
It is working fine for GOOGLE but from nowhere I am getting process/steps of how to use third party authentication for OPENID.
Please tell me if you know how to authenticate it.
