During the first step with execute: "composer require dfoxx/laravel-shibboleth", return the following error, is there anything I missed?

First off, thanks for writing this, it seems to be very useful. However I do have a few questions, which may just be me projecting my use case onto the package, rather than taking the package for what it is.

I have a Shibboleth SP set up, and am correctly getting requests forwarded to my Laravel project, and was looking for a way to use Shibboleth for authentication, which this library seems to provide.
After following the the various calls to and from the Laravel Framework, it seems to me that this package expects all users to already have their credentials (unity_id/SHIB_UID) stored in the Users table. Is this the case? If so, do you have a recommended way to add a user to the table if they are not yet present (and thus can't be authenticated)? It is my understanding that the IdP/SP architecture should allow SP to not do any checking of authenticity, which this package seems to do in it's call to attempt and retrieveByCredentials.

If any of my understanding is incorrect, I would greatly appreciate it if you let me know; I'm fairly new to both Laravel and Shibboleth.
