From the `Authorization rules/Computers` page, select `Add...` to create a new rule. Select the tenant, directory, device group, or computer you want to assign access to, and provide a friendly description for this rule. This will appear in audit logs if a user is granted access. Expand the `Access control` section and select `Edit Permissions...` to open the ACL editor. ![](https://1500666603-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FzPrDxVWpXXpSNTpkDVnR%2Fuploads%2Fgit-blob-b0d6bcb139913df7dd1c1a85ed9f3d4c91f032bf%2Fui-page-authz-editsecurity-bitlocker.png?alt=media) If you'd like to be notified when someone accesses a BitLocker recovery password, select the notification channels you'd like to send to for success and failure events. ## Step 4: Validate access Log in to the Access Manager web app as an authorized user, and request access to the recovery password for a computer. If you have performed the steps correctly, you should be able to see the machine's recovery password. If passwords cannot be retrieved, double check that you have followed the steps in this article, and see the [troubleshooting guide](/ams/v3.0/help-and-support/troubleshooting.md) for how to find the Access Manager server logs to help understand and resolve the issue. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.lithnet.io/ams/v3.0/configuration/deploying-features/setting-up-bitlocker/setting-up-bitlocker-ad.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
