Sorry to hear that you are having difficulties.
You guys do the download thing to trial, be a piece of cake but the install isnt nearly as smooth as you think.
Can you elaborate on any difficulties that you had attempting to install FusionAuth locally?
Simple a couple of SPs against your SAML IDP and I will know if we are in the play.
If you could elaborate on what you looking for I may be able to assist further.
Below is our existing documentation:
SAML as IdP:
