Direct login from Laravel (PHP)

[Aniket Das]

Hi,
I'm very new to RainLoop
I was trying to setup Rainloop SSO in my Laravel project.
Basically, I store the IMAP credentials in my Laravel Backend application.
And I want that users can directly login to Rainloop just by redirecting from Laravel.

I'm hosting both applications like this:
laravelapp.domain.com
webmail.domain.com

I came across this example:
https://github.com/RainLoop/rainloop-webmail/wiki/SSO-example

But I'm not sure, how exactly to use it,
Do we have to install something on my Laravel app, that will let us generate the SSO URL?
