SQL installation options

Access Manager requires a Microsoft SQL Server 2019 or higher database. The setup program can install a pre-configured instance of SQL express, or you can choose to use an existing SQL server, or even an Azure SQL database.

Using the pre-configured SQL Express instance

During installation, you can choose to have a pre-configured instance of SQL Express installed. The installer will create and configure a new SQL express instance (named AMS) on the local machine. Access to the database will be restricted to local administrators and the AMS service account.

This is suitable for small to medium-sized installations of Access Manager, and has a number of benefits such as being completely configured and managed by the AMS service itself. Do note that SQL express has several limitations that you will need to consider;

1 GB maximum memory used by the database engine
10 GB maximum database size
1 MB maximum buffer cache
Limited to the lesser of one (1) CPU socket or four (4) cores

For larger installations of Access Manager, you should consider using SQL server Standard or Enterprise edition.

If you are using the high-availability feature of Access Manager, you cannot use SQL Express. The SQL instance will need to be installed on a separate computer. Alternatively, use an Azure SQL or Amazon RDS database configured for high availability.

If you plan to use SQL Express, but the server you are installing on does not have an internet connection, then download the SQL Express installer and copy it to the server. You'll be prompted to provide this file during setup.

Using SQL Standard or Enterprise Edition

If you are running Access Manager in a large environment, or SQL express is otherwise not suitable, you can set up the AMS database on an SQL instance of your choosing. You must manually set up your instance, and create the database, before running the installer. During installation, you will be prompted for the server and instance name.

The database should be called AccessManager and the AMS service account must be added to the db_owner role of the database. Your database administrator can do this for you, or you can use the script below to create a new database with the default settings, and assign the correct permissions.

Installation steps

Use the following steps to manually create the database, allowing you to specify advanced properties like where the database files will be located, how big they should be initially and how much they should grow by, and what recovery mode to use.

Create a new database on the SQL server with the name AccessManager.
Create a login for the service account
Map the service account login to the AccessManager database
Add the service account to the db_owner role for the AccessManager database
Once these steps are complete, you can run the AMS installer, and specify your SQL server name and instance when prompted

Alternatively, you can use the following script to create a basic database with default settings. Note, that the default settings may not result in a database that is suitable for production use. You should ensure that at least the following settings are appropriate for your environment

Database file location
Database initial size and auto growth settings
Ensure the recovery mode matches your backup strategy and recovery point objectives

Using Azure SQL

Using an Azure SQL database is fully supported by Access Manager. You'll need to create an empty database before running the installer, and create a login for the AMS service to use.

Installation steps

From the Azure Portal, create a new SQL Database resource
Follow the wizard prompts, specifying the database name, and instance type as appropriate. We recommend you use the name AccessManager
Once the database has been provisioned, open the new resource
Select the Query editor option from the left menu, and authenticate to the instance
In the query editor window, paste the following code after modifying the password field to contain your own strong password

CREATE USER [svc-lithnetams] WITH password='your-password-here';
EXEC sp_addrolemember 'db_owner', 'svc-lithnetams';

Run the code to create a user in the database for the service account to use
From the menu on the left-hand side, expand Settings, select Connection Strings, and copy the ADO.NET (sql authentication) connection string
Modify the username and password in the connection string to contain the username and password you created earlier. Your connection string should look similar to below

Server=tcp:ams.database.windows.net,1433;Initial Catalog=AccessManager;Persist Security Info=False;User ID=svc-lithnetams;Password='your-password-here';MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

Once these steps are complete, you can run the AMS installer, and provide the connection string when prompted.

Using Amazon RDS

Using an AWS RDS Microsoft SQL database is fully supported by Access Manager. You'll need to create an empty database before running the installer, and create a login for the AMS service to use.

Installation steps

From the AWS Console, create a new Microsoft SQL Server RDS resource
Select the appropriate options and instance configuration for your environment
Once the server has been provisioned, ensure you allow the AMS server access to the RDS instance via the appropriate security groups
Using Microsoft SQL Management Studio, connect to the RDS instance using the admin credentials created during the setup process
In the query editor window, paste the following code after modifying the password field to contain your own strong password


CREATE LOGIN [svc-lithnetams] WITH password='your-password-here';
GO

-- Get the SQL Server data path.
DECLARE @data_path nvarchar(256);       
SET @data_path = (SELECT SUBSTRING(physical_name, 1, CHARINDEX(N'master.mdf', LOWER(physical_name)) - 1)
        FROM master.sys.master_files
        WHERE database_id = 1 AND file_id = 1);

EXECUTE ('
CREATE DATABASE [AccessManager]
 CONTAINMENT = NONE
 ON  PRIMARY 
( NAME = N''AccessManager'', FILENAME = "' + @data_path + 'AccessManager.mdf", SIZE = 1048576KB , FILEGROWTH = 131072KB )
 LOG ON 
( NAME = N''AccessManager_log'', FILENAME = "' + @data_path + 'AccessManager.ldf", SIZE = 524288KB , FILEGROWTH = 65536KB )
')

GO
USE [AccessManager]

CREATE USER [svc-lithnetams] FOR LOGIN [svc-lithnetams]
EXEC sp_addrolemember 'db_owner', 'svc-lithnetams';

Using the connecting string template below, modify the Server, User ID and Password variables to match the RDS endpoint and service credentials you created

Server=tcp:amsdb.xxxxx.us-east-1.rds.amazonaws.com,1433;Initial Catalog=AccessManager;Persist Security Info=False;User ID=svc-lithnetams;Password=your-password-here;MultipleActiveResultSets=False;Connection Timeout=30;

Once these steps are complete, you can run the AMS installer, and provide the connection string when prompted.

Security considerations

It is important to secure access to your database. It contains information used by computers to authenticate to the AMS server, as well as their group membership.

We recommend that if possible, the database server is kept dedicated for Access Manager, and not shared with other applications. Administrators of the database server should be restricted to AMS admins only.
