Automatically pull user attributes, group memberships, and organizational units from your LDAP directory into Cerbos policy evaluations, no application code changes required.
Automatically enrich authorization requests with user profiles, group memberships, and organizational units from your LDAP directory
Configurable TTLs cache enrichment results to balance data freshness against evaluation latency
Identity enrichment happens at the policy layer, your application code stays clean
Authorization decisions are only as good as the data behind them. LDAP provides real-time context (user profiles, group memberships, or external attributes) that makes Cerbos policies richer and more accurate.
Cerbos lets you write fine-grained, context-aware authorization policies in human-readable YAML. With LDAP as a context source, those policies can evaluate attributes beyond what's in the initial request.
Because enrichment happens at the policy layer, your application code stays clean, no custom plumbing to fetch and merge identity data before making authorization calls.
LDAP directories remain the backbone of identity management in many organizations, especially those with on-premises infrastructure, legacy systems, or regulated environments. Cerbos identity enrichment connects directly to your LDAP directory, making user attributes, group memberships, and organizational unit data available in your authorization policies.
Many organizations have decades of identity data in LDAP that they cannot easily migrate. Cerbos lets you build modern, fine-grained authorization policies on top of your existing directory without requiring a migration to a cloud identity provider.
LDAP identity enrichment is available as part of Cerbos enterprise. Talk to us to learn more about enriching your authorization decisions with LDAP directory data.
Cerbos queries your LDAP directory at evaluation time to fetch the user's attributes, group memberships, and organizational unit. This data is available as principal attributes in your policies, enabling rules based on any directory attribute.
The authentication integration relies on your application to query LDAP and pass identity data to Cerbos. Identity enrichment is handled by Cerbos itself, it queries the directory directly at authorization time, so your application only needs to provide a user identifier.
Cerbos supports any LDAPv3-compatible directory, including Active Directory, OpenLDAP, 389 Directory Server, FreeIPA, and Oracle Internet Directory. Connections support LDAPS and StartTLS for encryption, and client certificate authentication for mutual TLS.




What is Cerbos?
Cerbos is an end-to-end enterprise authorization software for Zero Trust environments and AI-powered systems. It enforces fine-grained, contextual, and continuous authorization across apps, APIs, AI agents, MCP servers, services, and workloads.
Cerbos consists of an open-source Policy Decision Point, Enforcement Point integrations, and a centrally managed Policy Administration Plane (Cerbos Hub) that coordinates unified policy-based authorization across your architecture. Enforce least privilege & maintain full visibility into access decisions with Cerbos authorization.
