In order to install the Access Manager Service, the following prerequisites must be met;
Windows Server 2016 or later
8.0.0 or later installed
8.0.0 or later installed
Microsoft SQL Express 2019, if hosting the database locally, or a separate SQL Standard or Enterprise edition server. (SQL express is installed by default)
If you plan to use SQL Express, but the server you are installing on does not have an internet connection, then and copy it to the server. You'll be asked to specify the installation file during setup.
A TLS certificate for the AMS website
The installer can download the prerequisites when an internet connection is available. You can read the guide on for automatic prerequisite installation.
The Access Manger Service needs to run under the context of a domain user account. We strongly recommend using a group-managed service account for this purpose. which includes a script to get you up and running quickly.
Do not grant any specific permissions to this account and most certainly don't add it to super-privileged groups like Domain Admins. As you go through the setup process, you'll be given scripts to delegate permissions specific to the functionality you want to enable.
Determine the host name you will use to access AMS and request an SSL certificate from your certificate provider. Install the certificate in the 'personal' store of the local computer.
You can use the following command to create a self-signed SSL certificate suitable for testing, replacing the DNS name with the name of your AMS server
Run the AMS installation package. Follow the prompts to install the application and provide the service account created in step 1 when prompted.
Launch the Access Manager Service configuration tool from the start menu.
From the Host configuration page, click the Select from store... button and select the certificate you installed in step 2.
Select the option to enable the web app, to allow users to request access to computers and roles. If you plan on using the Lithnet Access Manager Agent, then select the option to enable the Access Manager API.
Click File, then Save.
You'll need to configure an outbound mail server in order to receive audit alerts via email.
In order to ensure that your service is not used inappropriately, you can place limits of the number of requests a user can make in a given time. You should set these high enough that your users are not going to encounter rate limit issues under normal usage, but low enough to limit the impact of inappropriate or malicious usage of the service.
If you put AMS behind a reverse proxy or load balancer, you'll need to configure IP address detection. This is to ensure that AMS logs the correct IP address in audit logs, and applies rate limiting correctly.
Configure the user interface as per your organization's requirements. You can customize the name of the application, provide your own logo and even provide some custom policy text for the access request page.
AMS has a powerful auditing engine that allows you to receive notifications when access is granted or denied to a user. AMS logs audit events to the Windows event log all the time, but you can also send audit events via email, through a custom PowerShell script, or even to Slack or Microsoft Teams using a web hook.
From the Active Directory tab, check that the AMS service account is a member of the Windows Authorization Access Group and Access Control Assistance Operators built-in groups within each domain. This is required for the AMS service account to be able to calculate access permissions for users and computers within these domains. If any permissions are missing, use the Grant permission button to generate a script to grant them.
You will need to restart the service to pick up the new group membership in the local domain.
Now that you have the core application set up, you can configure the Access Manager features you are interested in;
Download the latest version from the page.
Download and install the , or if your server has internet access, you can let the installer download and install these for you
AMS supports several authentication providers. Read the guide on and choose an authentication provider. We strongly recommend using a modern authentication provider that supports strong authentication and can enforce multifactor authentication. While integrated windows authentication is provided, we recommend you only use this for testing purposes.
