# Casdoor Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

Casdoor is a UI-first centralized authentication / Single-Sign-On (SSO) platform supporting OAuth 2.0, OIDC and SAML, integrated with Casbin RBAC and ABAC permission management. This document covers configuring Casdoor identity provider support with MinIO.

## Prerequisites

# AssumeRoleWithWebIdentity [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

## Introduction

MinIO supports the standard AssumeRoleWithWebIdentity STS API to enable integration with OIDC/OpenID based identity provider environments. This allows the generation of temporary credentials with pre-defined access policies for applications/users to interact with MinIO object storage.

func (p *providerCfg) GetRoleArn() string {
	if p.RolePolicy == "" {
		return ""
	}
	return p.roleArn.String()
}

// UserInfo returns claims for authenticated user from userInfo endpoint.
//
// Some OIDC implementations such as GitLab do not support
// claims as part of the normal oauth2 flow, instead rely
// on service providers making calls to IDP to fetch additional
// claims available from the UserInfo endpoint
