Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [Set-ADAccountAuthenticationPolicySilo](https://learn.microsoft.com/en-us/powershell/module/activedirectory/set-adaccountauthenticationpolicysilo?view=windowsserver2025-ps) from Microsoft supports the following bounded statements: - At SYNOPSIS, Microsoft states: “Modifies the authentication policy or authentication policy silo of an account.” The research record locates this support at SYNOPSIS. - At DESCRIPTION, Microsoft states: “The Set-ADAccountAuthenticationPolicySilo cmdlet modifies the authentication policy or authentication policy silo of an account.” The research record locates this support at DESCRIPTION. Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services and the conditions the source actually describes. ## What the source does not establish The cited page and retained statements do not establish the current state of any DSE or customer environment, prove that the documented configuration is applicable, or authorize a production change. Confirm supported versions, dependencies, and the current live source before use. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials are healthy. Documented options are review inputs, not universal mandates. ## Applicability questions - For source statement 1 at SYNOPSIS, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at DESCRIPTION, which observable configuration, record, or test can confirm applicability here? - What inventory proves which parts of Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services are in and out of scope? - Which condition in Active Directory replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials 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. Use a two-person review for the source interpretation and the resulting operational decision. Record the source location, examined part of Active Directory objects, search bases, domain controllers, delegated roles, cmdlet parameters, and the DNS paths used to locate directory services, 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 replication, Windows DNS, domain-controller location, time, network reachability, privileges, and protected credentials and sanitize protected material before retention. ## Verification and evidence Evidence should let another reviewer reproduce this decision. Retain observations beside the traced locations SYNOPSIS; DESCRIPTION. Favor sanitized command transcripts, parameter records, directory exports, authorization records, DNS locator tests, and before-and-after state, linked to stable identifiers, time, and operator. Label this evidence set DSE-20260827-149 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. 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 - [Set-ADAccountAuthenticationPolicySilo](https://learn.microsoft.com/en-us/powershell/module/activedirectory/set-adaccountauthenticationpolicysilo?view=windowsserver2025-ps) — Microsoft ## Primary reference - Name: Set-ADAccountAuthenticationPolicySilo - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/powershell/module/activedirectory/set-adaccountauthenticationpolicysilo?view=windowsserver2025-ps - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Set-ADAccountAuthenticationPolicySilo: change adaccount authentication policy silo with before-and-after evidence,” DSE Security, https://update.dsesecurity.com/updates/set-adaccountauthenticationpolicysilo-change-adaccount-authentication-policy-silo-with-before-and/ 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.
