OpenLDAP & Kerberos

OpenLDAP and Kerberos are the open-source foundations of centralised identity management. OpenLDAP provides the directory, storing users, groups, and organisational data, while Kerberos handles authentication with strong, ticket-based security. Together, they replace Active Directory and other proprietary identity platforms.

The Active Directory alternative

Active Directory is deeply embedded in many organisations, but it ties your identity infrastructure to Microsoft. OpenLDAP and Kerberos provide the same core capabilities: centralised authentication, group-based access control, and single sign-on, without the vendor dependency or per-user licensing.

Standards-based identity

Both OpenLDAP and Kerberos are based on open standards (LDAP and the Kerberos protocol), meaning they interoperate with virtually every application and operating system. Linux, macOS, and even Windows can authenticate against them, making them a truly vendor-neutral identity backbone.

Our expertise

We help companies plan and evaluate identity infrastructure with OpenLDAP and Kerberos, advising on directory schema design, authentication architecture, and transition strategies from Active Directory.
