Hey guys, hopefully someone can answer this question.

Pretty new to Zoho, so just poking around.

I have a PHP app that requires users to authenticate with a database. I want to be able to add this app to zoho for other users in my group to access. It seems like my app runs in an iFrame on zoho, so my question is, is there anyway for me to bypass authentication and use Zoho authentication of the user that is currently trying to access my app.

In other words, user clicks on my app from within Zoho, I know this, then authenticate with zoho credentials as opposed to authenticating with my apps built in authentication?
