Identity & Access Management (IAM)
Securing modern information systems through robust identity pillars.
In a zero-trust world, identity is the new perimeter. We build hardened authentication backbones designed for enterprises that cannot compromise on security or compliance.
What is Identity & Access Management (IAM)?
Identity and access management has become an essential pillar for securing modern information systems. Our deep expertise centers on OpenLDAP deployment, strict Kerberos implementations for both services and users, and highly secure smart card-based access mechanisms.
Kerberos Authentication Flow Explained
Kerberos is a network authentication protocol that uses symmetric-key cryptography and a trusted third party (the KDC — Key Distribution Center) to authenticate users and services without ever sending passwords over the network. The flow works as follows: When a user logs in, their client requests a Ticket-Granting Ticket (TGT) from the Authentication Server (AS). The AS verifies the user's credentials against the LDAP directory and responds with a TGT encrypted with the user's key. When the user needs to access a service (e.g., a file server or web application), their client presents the TGT to the Ticket-Granting Server (TGS) and requests a service ticket. The TGS issues a service ticket encrypted with the target service's secret key. The client presents this service ticket to the target service, which decrypts it with its own key. The service now knows with cryptographic certainty that the user is authenticated — and no password was ever transmitted. This is why Kerberos is the gold standard for enterprise authentication in environments where security cannot be compromised.

Frequently Asked Questions
Yes. For many organizations, a well-architected OpenLDAP and Samba suite provides all the group policy and directory services of AD without the massive licensing costs.
We deploy in phased approaches, allowing fallback authentication until specific departments are fully trained and equipped with hardware tokens.
Yes. We perform schema mapping, bulk user export/import, and reconfigure all downstream applications to authenticate against the new LDAP backend with zero downtime.
We create dedicated Kerberos principals for each service and configure keytab files for automatic, password-less authentication. This eliminates hardcoded credentials in application configurations.
Absolutely. We configure PAM modules (pam_pkcs11) to authenticate users via smart card against the LDAP directory, providing seamless login on Linux, macOS, and Windows.
