Ports Required for Active Directory and PKI: A Complete Guide
Essential network ports and protocols for AD and PKI infrastructure. Join us to learn how to configure your firewalls correctly.
Every enterprise network depends on Active Directory and Public Key Infrastructure (PKI) for authentication, authorization, and secure communications.
However, these services require specific network ports to function properly and misconfigurations can bring your infrastructure to a halt.
Whether you’re deploying domain controllers, setting up certificate authorities, or configuring firewalls, understanding these port requirements is critical for:
- Seamless Authentication: Ensuring users can log in without delays.
- Certificate Enrollment: allowing devices to request and renew certificates automatically.
- Replication: Keeping your directory data consistent across all sites.
What We Will Cover
- TCP/UDP 389 & 636: LDAP and LDAPS protocols.
- TCP 88: Kerberos authentication.
- TCP 135 & 445: RPC and SMB requirements for certificate enrollment.
- OCSP & CRL: Why HTTP (Port 80) is still required for revocation checking.
