Snipe-IT SAML no JOY

Currently running Snipe-IT on Unraid, and it’s been working well. Looking to set up SAML.
following the documentation to setup SAML I get a

Success: Settings updated successfully.

But when trying to sign in using SAML, I get an error.

Error There was a problem while trying to log you in, please try again.

Wondering if I’m missing environment variables specific for SAML to work properly.
