Login GUI accepts user/pass but keeps asking to login

Does there exist any type of tutorial(s) that would be able to guide someone through configuring FreeBSD to match the GUI of FreeNAS as much as possible?

I doubt that anyone has even tried that. FreeNAS is specialized system for one purpose (NAS) and reason why it was created was simply that vanilla FreeBSD was not suitable for building such specialized solutions because it would have been enormous amount of work. You could easily mimic the look and feel of the FreeNAS GUI but getting the same functionality is out of reach completely.

You can come close to the look by matching whichever windowmanger and other desktop programs it uses, if its available. You'd have to research those programs documentation, which aside from FreeBSD's configuration directories, much wouldn't be on FreeBSD forums.

What kpa said is usually true for most applications. It's better to say it's FreeBSD based, because to some extent it varies from FreeBSD.

PHP? FreeBSD rc system thrown out? Uhm ... I won't mention FreeNAS anymore then.

Apologies for my quick shot. I never actually used FreeNAS. I just found it mentioned frequently and had a quick look at it. But I had no need because obviously I personally would build everything with FreeBSD.
But then the OP here isn't that experienced a user plus he wanted a nice GUI (something I personally couldn't care less about).
