Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Certificate Enrollment Web Service overview](https://learn.microsoft.com/en-us/windows-server/identity/ad-cs/certificate-enrollment-web-service) from Microsoft supports the following bounded statements: - Certificate Enrollment Web Service accepts enrollment over HTTPS for users and computers. The research record locates this support at Opening overview. - Together with the policy service, it supports policy-based enrollment for non-domain or temporarily disconnected domain clients. The research record locates this support at Opening overview. Only the traced statements above are asserted as source facts. Apply the review to certification authorities, templates, enrollment paths, certificate subjects, private-key handling, and delegated PKI roles after confirming that the source and deployed context match. ## What the source does not establish Authentication type, delegation, CA connectivity, and load balancing must be designed together. A correct source interpretation can still be inapplicable to a particular design. Confirm Active Directory, Windows DNS, time, domain-controller reachability, HTTP or LDAP publication, and protected administrative identities, ownership, and change authority instead of treating documented behavior as a deployment guarantee. ## Applicability questions - For source statement 1 at Opening overview, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at Opening overview, which observable configuration, record, or test can confirm applicability here? - What inventory proves which parts of certification authorities, templates, enrollment paths, certificate subjects, private-key handling, and delegated PKI roles are in and out of scope? - Which condition in Active Directory, Windows DNS, time, domain-controller reachability, HTTP or LDAP publication, and protected administrative identities must be healthy before evidence is trustworthy? - What result would disprove the working assumption and return the issue to the owner? ## DSE recommendation: DSE recommends using the cited source as the evidence anchor for this decision. Begin by recording scope and current state before deciding whether a change is warranted. Record the source location, examined part of certification authorities, templates, enrollment paths, certificate subjects, private-key handling, and delegated PKI roles, observed and expected states, owner, and reason for deviation. If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for Active Directory, Windows DNS, time, domain-controller reachability, HTTP or LDAP publication, and protected administrative identities and sanitize protected material before retention. ## Verification and evidence Keep the source locations Opening overview; Opening overview adjacent to the sanitized artifacts used for comparison. Prefer CA and template exports, enrollment tests, certificate chains, access-control entries, event logs, and revocation-path checks, with enough identity and timing data for an independent recheck. Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee. ## Official references - [Certificate Enrollment Web Service overview](https://learn.microsoft.com/en-us/windows-server/identity/ad-cs/certificate-enrollment-web-service) — Microsoft ## Primary reference - Name: Certificate Enrollment Web Service overview - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/windows-server/identity/ad-cs/certificate-enrollment-web-service - Source publication date: 2025-03-28 ## Citation and use Preferred citation: “Design Certificate Enrollment Web Service for off-domain clients,” DSE Security, https://update.dsesecurity.com/updates/design-certificate-enrollment-web-service-for-off-domain-clients/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
