## What it is
A Go library providing a partial implementation of the SAML standard for identity federation. It supports building both Service Providers (via samlsp middleware) and Identity Providers (via samlidp) for SSO authentication flows.

## Use cases
- add SAML SSO login to a Go web application
- implement a SAML service provider in Go
- act as a SAML identity provider for testing
- authenticate users via Okta, Azure AD, or samltest.id
- protect HTTP endpoints with SAML middleware
- exchange SAML metadata with identity providers

## When to choose
- your Go app needs to delegate authentication to a SAML identity provider
- you need enterprise SSO integration via SAML 2.0
- you want middleware that handles SAML endpoints and session checks
- you need a test identity provider for SAML development

## When to avoid
- you need OAuth2 or OpenID Connect instead of SAML
- you need a complete, fully-featured identity provider product
- your stack is not Go
- you need full SAML standard coverage since the implementation is partial

## Facets
- artifact type: library
- maturity: stable
- function: auth, middleware, http-server, security
- domain: security, web-development, backend, apis
- platform: go, windows, cross-platform
