Clerk Enterprise RBAC

Overview

Implement enterprise-grade SSO, role-based access control, and organization management.

Prerequisites

• Clerk Enterprise tier subscription
• Identity Provider (IdP) with SAML/OIDC support
• Understanding of role-based access patterns
• Organization structure defined

Instructions

Step 1: Configure SAML SSO

In Clerk Dashboard

1. Go to Configure > SSO Connections
2. Add SAML Connection
3. Configure IdP settings:
   • ACS URL:

     https://clerk.yourapp.com/v1/saml

   • Entity ID: Provided by Clerk
   • Download SP metadata

IdP Configuration (Example: Okta)

<!-- SAML Attributes to map -->
<saml:Attribute Name="email">
  <saml:AttributeValue>user.email</saml:AttributeValue>
</saml:Attribute>
<saml:Attribute Name="firstName">
  <saml:AttributeValue>user.firstName</saml:AttributeValue>
</saml:Attribute>
<saml:Attribute Name="lastName">
  <saml:AttributeValue>user.lastName</saml:AttributeValue>
</saml:Attribute>
<saml:Attribute Name="role">
  <saml:AttributeValue>user.role</saml:AttributeValue>
</saml:Attribute>

Step 2: Define Roles and Permissions

// lib/permissions.ts

// Define all permissions in your system
export const PERMISSIONS = {
  // Resource: Action
  'users:read': 'View user list',
  'users:write': 'Create/update users',
  'users:delete': 'Delete users',
  'settings:read': 'View settings',
  'settings:write': 'Modify settings',
  'billing:read': 'View billing info',
  'billing:write': 'Manage billing',
  'reports:read': 'View reports',
  'reports:export': 'Export reports'
} as const

export type Permission = keyof typeof PERMISSIONS

// Define roles with their permissions
export const ROLES = {
  'org:admin': [
    'users:read', 'users:write', 'users:delete',
    'settings:read', 'settings:write',
    'billing:read', 'billing:write',
    'reports:read', 'reports:export'
  ],
  'org:manager': [
    'users:read', 'users:write',
    'settings:read',
    'reports:read', 'reports:export'
  ],
  'org:member': [
    'users:read',
    'reports:read'
  ],
  'org:viewer': [
    'reports:read'
  ]
} as const satisfies Record<string, Permission[]>

export type Role = keyof typeof ROLES

Step 3: Permission Checking

// lib/auth-permissions.ts
import { auth } from '@clerk/nextjs/server'
import { ROLES, Permission, Role } from './permissions'

export async function hasPermission(permission: Permission): Promise<boolean> {
  const { orgRole } = await auth()

  if (!orgRole) return false

  const role = orgRole as Role
  const rolePermissions = ROLES[role]

  if (!rolePermissions) return false

  return rolePermissions.includes(permission)
}

export async function requirePermission(permission: Permission): Promise<void> {
  const allowed = await hasPermission(permission)

  if (!allowed) {
    throw new Error(`Permission denied: ${permission}`)
  }
}

// Decorator pattern for API routes
export function withPermission(permission: Permission) {
  return async function(
    handler: (req: Request) => Promise<Response>
  ): Promise<(req: Request) => Promise<Response>> {
    return async (req: Request) => {
      const allowed = await hasPermission(permission)

      if (!allowed) {
        return Response.json(
          { error: 'Permission denied', required: permission },
          { status: 403 }
        )
      }

      return handler(req)
    }
  }
}

Step 4: Protected Routes with RBAC

// middleware.ts
import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'
import { NextResponse } from 'next/server'

const isPublicRoute = createRouteMatcher(['/', '/sign-in(.*)', '/sign-up(.*)'])
const isAdminRoute = createRouteMatcher(['/admin(.*)'])
const isBillingRoute = createRouteMatcher(['/billing(.*)'])

export default clerkMiddleware(async (auth, request) => {
  const { userId, orgRole } = await auth()

  if (isPublicRoute(request)) {
    return NextResponse.next()
  }

  if (!userId) {
    return auth.redirectToSignIn()
  }

  // Admin routes require admin role
  if (isAdminRoute(request)) {
    if (orgRole !== 'org:admin') {
      return NextResponse.redirect(new URL('/unauthorized', request.url))
    }
  }

  // Billing routes require admin or manager
  if (isBillingRoute(request)) {
    if (!['org:admin', 'org:manager'].includes(orgRole || '')) {
      return NextResponse.redirect(new URL('/unauthorized', request.url))
    }
  }

  return NextResponse.next()
})

Step 5: Organization Management

// lib/organization.ts
import { clerkClient, auth } from '@clerk/nextjs/server'

export async function createOrganization(name: string, slug: string) {
  const { userId } = await auth()
  const client = await clerkClient()

  const org = await client.organizations.createOrganization({
    name,
    slug,
    createdBy: userId!
  })

  return org
}

export async function inviteToOrganization(
  orgId: string,
  email: string,
  role: string
) {
  const client = await clerkClient()

  const invitation = await client.organizations.createOrganizationInvitation({
    organizationId: orgId,
    emailAddress: email,
    role,
    inviterUserId: (await auth()).userId!
  })

  return invitation
}

export async function updateMemberRole(
  orgId: string,
  userId: string,
  role: string
) {
  const client = await clerkClient()

  await client.organizations.updateOrganizationMembership({
    organizationId: orgId,
    userId,
    role
  })
}

export async function getOrganizationMembers(orgId: string) {
  const client = await clerkClient()

  const { data: members } = await client.organizations.getOrganizationMembershipList({
    organizationId: orgId
  })

  return members
}

Step 6: React Components with RBAC

// components/permission-gate.tsx
'use client'
import { useAuth, useOrganization } from '@clerk/nextjs'
import { ROLES, Permission, Role } from '@/lib/permissions'

interface PermissionGateProps {
  permission: Permission
  children: React.ReactNode
  fallback?: React.ReactNode
}

export function PermissionGate({
  permission,
  children,
  fallback = null
}: PermissionGateProps) {
  const { orgRole } = useAuth()

  if (!orgRole) return fallback

  const role = orgRole as Role
  const permissions = ROLES[role] || []

  if (!permissions.includes(permission)) {
    return fallback
  }

  return <>{children}</>
}

// Usage
function AdminPanel() {
  return (
    <div>
      <h1>Dashboard</h1>

      <PermissionGate permission="users:write">
        <button>Add User</button>
      </PermissionGate>

      <PermissionGate permission="billing:read">
        <BillingSection />
      </PermissionGate>

      <PermissionGate
        permission="settings:write"
        fallback={<p>Contact admin for settings access</p>}
      >
        <SettingsForm />
      </PermissionGate>
    </div>
  )
}

Step 7: API Route Protection

// app/api/admin/users/route.ts
import { auth } from '@clerk/nextjs/server'
import { hasPermission } from '@/lib/auth-permissions'

export async function GET() {
  const { userId, orgId } = await auth()

  if (!userId || !orgId) {
    return Response.json({ error: 'Unauthorized' }, { status: 401 })
  }

  if (!await hasPermission('users:read')) {
    return Response.json({ error: 'Forbidden' }, { status: 403 })
  }

  // Fetch users scoped to organization
  const users = await db.user.findMany({
    where: { organizationId: orgId }
  })

  return Response.json(users)
}

export async function POST(request: Request) {
  const { userId, orgId } = await auth()

  if (!userId || !orgId) {
    return Response.json({ error: 'Unauthorized' }, { status: 401 })
  }

  if (!await hasPermission('users:write')) {
    return Response.json({ error: 'Forbidden' }, { status: 403 })
  }

  const data = await request.json()

  const user = await db.user.create({
    data: {
      ...data,
      organizationId: orgId,
      createdBy: userId
    }
  })

  return Response.json(user)
}

Output

• SAML SSO configured
• Roles and permissions defined

• Organization management

Error Handling

Error	Cause	Solution
SSO login fails	Misconfigured IdP	Check attribute mapping
Permission denied	Missing role	Review role assignments
Org not found	User not in org	Prompt org selection
