# Single Sign-On

> Use Enterprise SSO features on self-hosted OpnForm

Self-hosted Enterprise unlocks advanced SSO features for teams that need centralized identity management beyond the Community self-hosted limits.

<Info>
  OIDC SSO is available on self-hosted Community instances without an
  Enterprise license, but the instance remains limited to 2 users total.
  Enterprise is required to add more than 2 users and to use SAML or LDAP SSO.
</Info>

## What this unlocks

Enterprise SSO covers:

* SAML SSO
* LDAP SSO
* More than 2 self-hosted users when using OIDC provisioning

OIDC configuration is documented in detail and can be used on Community self-hosted instances within the 2-user limit. SAML and LDAP availability depends on the Enterprise features enabled for your installation.

## Before you start

Make sure you have:

* An active self-hosted Enterprise license with SSO enabled for SAML or LDAP
* Workspace admin access
* Identity provider credentials and allowed redirect URI configuration

## Configure OIDC SSO

See [OIDC SSO Configuration](/configuration/oidc-sso) for provider setup, redirect URI behavior, field mappings, group-to-role mappings, and force login mode.
