Do I need role-based access tied to SSO groups?

Not always — but in most organizations, yes, you usually want role-based access tied to SSO groups if you need scalable, auditable access control.

When you should use it

Use SSO group–based RBAC if you need:

• Centralized user management in your IdP (Okta, Azure AD, Google Workspace, etc.)
• Automatic onboarding/offboarding
• Least-privilege access
• Auditability and easier reviews
• Fewer manual permission changes in the app

When you might not need it

You may not need group-based RBAC if:

• The app is very small/internal
• Only a few users ever access it
• Permissions are simple and rarely change
• You’re fine managing access directly in the app

Common best practice

A good pattern is:

• SSO handles authentication
• IdP groups map to application roles
• The app enforces authorization based on those roles

Example:

• Finance-Admins → admin
• Support-Agents → support
• Employees → read-only

Important nuance

You do not need every permission to come from SSO groups. Often:

• High-level roles come from groups
• Fine-grained permissions are managed inside the app

If you want, I can help you decide based on your setup — for example, whether you’re using SAML, OIDC, Okta, Azure AD, or something else.
