Our verdict on LemonLDAP::NG

LemonLDAP::NG is a self-hosted web single sign-on and access-management platform for organizations protecting internal and external applications. It combines authentication, authorization, accounting, identity federation, session management, and application integration. Support for CAS, SAML 2.0, and OpenID Connect makes it suitable for teams connecting varied applications, while LDAP and Active Directory integration supports established directory environments. Its published platform coverage includes web, Linux, API, and self-hosted deployments.

The open-source model provides a free plan, making LemonLDAP::NG a strong fit for teams that want to operate their own identity layer without a listed paid-tier structure. The trade-off is ownership of the self-hosted deployment and its surrounding configuration. This model is better suited to organizations with Linux and web-server experience than to buyers seeking a managed SSO service. Common deployment options include Apache, Nginx, Plack, and Node.js handlers.

Its strongest area is control depth. Teams can apply adaptive authentication rules using contextual conditions such as network or device, define access rules by application attributes, groups, and URLs, and protect applications through HTTP headers with the Handler component. MFA options include TOTP, WebAuthn, Yubico OTP, email, RADIUS, and REST second factors. Session explorer, restrictions, and global logout add lifecycle control, while REST and SOAP services support portal and integration use cases. Choose LemonLDAP::NG when protocol breadth, self-hosting, and policy control matter most; choose another product if you want a managed operating model or AI features.
