# Vast.ai Enterprise RBAC

## Overview
Configure enterprise-grade access control for Vast.ai integrations.

## Prerequisites
- Vast.ai Enterprise tier subscription
- Identity Provider (IdP) with SAML/OIDC support
- Understanding of role-based access patterns
- Audit logging infrastructure

## Role Definitions

| Role | Permissions | Use Case |
|------|-------------|----------|
| Admin | Full access | Platform administrators |
| Developer | Read/write, no delete | Active development |
| Viewer | Read-only | Stakeholders, auditors |
| Service | API access only | Automated systems |

## Role Implementation

```typescript
enum Vast.aiRole {
  Admin = 'admin',
  Developer = 'developer',
  Viewer = 'viewer',
  Service = 'service',
}

interface Vast.aiPermissions {
  read: boolean;
  write: boolean;
  delete: boolean;
  admin: boolean;
}

const ROLE_PERMISSIONS: Record<Vast.aiRole, Vast.aiPermissions> = {
  admin: { read: true, write: true, delete: true, admin: true },
  developer: { read: true, write: true, delete: false, admin: false },
  viewer: { read: true, write: false, delete: false, admin: false },
  service: { read: true, write: true, delete: false, admin: false },
};

function checkPermission(
  role: Vast.aiRole,
  action: keyof Vast.aiPermissions
): boolean {
  return ROLE_PERMISSIONS[role][action];
}
```

## SSO Integration

### SAML Configuration

```typescript
// Vast.ai SAML setup
const samlConfig = {
  entryPoint: 'https://idp.company.com/saml/sso',
  issuer: 'https://vastai.com/saml/metadata',
  cert: process.env.SAML_CERT,
  callbackUrl: 'https://app.yourcompany.com/auth/vastai/callback',
};

// Map IdP groups to Vast.ai roles
const groupRoleMapping: Record<string, Vast.aiRole> = {
  'Engineering': Vast.aiRole.Developer,
  'Platform-Admins': Vast.aiRole.Admin,
  'Data-Team': Vast.aiRole.Viewer,
};
```

### OAuth2/OIDC Integration

```typescript
import { OAuth2Client } from '@vastai/sdk';

const oauthClient = new OAuth2Client({
  clientId: process.env.VAS
