This guide explains the configuration of multi-factor authentication (MFA) for VMware Horizon 8 utilizing Mirket as the identity provider. Prior configuration and deployment of VMware Horizon 8 are required before setting up MFA with Mirket.
VMware Horizon 8 firewall offers various MFA configuration modes. In this integration, we've configured RADIUS authentication with Mirket.
Before proceeding with these procedures, ensure the following:
You've completed the installation and configuration of the Mirket (go to Mirket Installation Steps).
Horizon Connection Server is connected to vCenter Server.
The vCenter Server directs a Virtual Machine installed with the Horizon Agent.
Within this setup, the Horizon Connection Server has published one or more applications accessible on the Virtual Machine with the Horizon Agent installed.
With a user account existing in the Active Directory domain, you can log in to the Connection Server using the Horizon Client and access published applications.
Access the Horizon Console with an administrator account.
Go to Settings > Servers > Connection Servers from the menu. Then choose the existing connection server.
Click on Edit. Select the Authentication tab. Then choose the RADIUS option from the 2-factor authentication dropdown list under the Advanced Authentication section.
Check the "Enforce 2-factor and Windows user name matching" and "Use the same user name and password for RADIUS and Windows authentication" checkboxes.
Choose the Create New Authenticator option from the Authenticator dropdown list.
Enter an authenticator name in the Authenticator Name field. In this instance, enter the authenticator name as "Mirket".
Click on Next. Input the IP address or host FQDN of the server where the Mirket is installed in the Hostname/Address field.
Input "1812" in the Authentication Port field. Then input "0" in the Accounting Port field.
Choose the "PAP" option from the Authentication Type dropdown list.
Input a shared secret key to communicate with the RADIUS server (Mirket Radius) in the Shared Secret field. In Mirket use this same secret key when configuring a RADIUS client resource.
Input "60" in the Server Timeout field. Then input "5" in the Max Attempts field.
Keep the remaining settings as default values.
Then click on Next and click on Finish to confirm settings.
Click on OK to confirm settings.
To enable Mirket to receive authentication requests from Horizon Connection Server, follow these steps:
Define Horizon Connection Server client as a RADIUS client resource within Mirket.
Create an authentication policy for the Horizon Connection Server RADIUS client resource or include it in an existing authentication policy.
Attach the Horizon Connection Server resource to the Mirket Radius.
Before starting, ensure that you have installed Mirket Radius Gateway from the Configuration > Gateway. To add a Radius Gateway to the Mirket, follow these steps:
Go to Configuration > Gateway and click on the Add Radius Gateway button.
On the displayed screen, enter a name for your Radius Gateway in the Name field.
Enter the SAM value of the gateway in the Sam Value field. In Mirket, user identification is done using the SAM (Security Account Manager) name. This is preferred over the standard username. This username is used for authentication and access controls.
Enter the IP address of the server where the gateway is installed in the Host IP Address field.
Enter the authentication port value you set for the gateway in the Auth Port field. The default value is 1812.
Enter the accounting port value you specified for the gateway in the Acc Port field. The default value is 1813. Note: After completing these fields, you must create a RADIUS client for the newly created RADIUS Gateway.
Click on the Add Radius Client option at the bottom of the displayed screen.
Enter a name for your Radius Client in the Radius Client field.
Enter the IP address of the client(firewall) that will communicate with the gateway in the IP Address field.
Enter the secret key that the client will communicate with the gateway in the Secret Key field.
Click on the Save button to confirm the settings.
After creating the Radius Gateway, click on the Download > Config from the menu on the right side of the gateway.
This option will generate a script related to the gateway, which will be displayed from the RADIUS Setup config file. The config file will automatically begin downloading once this option is selected.
Replace the existing config file in the "C:\MirketRadius" directory with the downloaded file. Alternatively, copy the displayed script and paste it into the config file in "C:\MirketRadius".
Then, restart the Mirket Radius Service.
You can check whether the Radius Gateway you created is active by navigating to Configuration > Gateway.
To set up multifactor authentication, make sure you have at least one user or group in Mirket.
If it is preferred to use a local user, you can first create a local group and then create a local user and make the user a member of the group. Alternatively, you can create a local user without creating a local group.
If it is preferred to use LDAP users, the priority External Source is created by pulling users from Active Directory or OpenLDAP in Mirket. Note: Before proceeding, ensure that you have installed Mirket LDAP Gateway. (Refer to create LDAP Gateway.)
Radius Rules define user access to resources and the authentication methods available (such as SMS, Approve / Deny, OTP, etc.).
First, you should follow these steps:
Go to Configuration > Radius Rules.
Click on the Add Radius Rule button.
On the displayed screen, enter a name for the rule in the Name field.
Enter the rule description in the Description field.
Select the Radius Client to which the rule will apply from the Radius Client dropdown list.
Enter the source IP addresses to which the rule will apply in the Source Adress field.
Select the source countries where the rule will be applied from the Source Country dropdown list.
Click on the Next button.
Specify whether the rule will be applied to a user or a group.
After specifying, click on the Next button.
Select the users or groups to which the rule will apply. Transfer your selections to the Selected Users/Groups table by clicking the arrow icon next to the Available Users/Groups table.
Click on the Next button.
Select the time period when the rule will run.
All: The rule will run every day.
Recurring: The rule will run on the specified days and times.
One Time: The rule will run within the date range you specify.
After selecting, click on the Next button.
Specify whether the user or group will be granted access based on the rule in the Action field.
Select the authentication provider to which the rule will apply from the Auth Method dropdown list.
Click on Save to confirm the settings.
To validate the integration between Mirket MFA and your VMware Horizon 8, perform authentication using a mobile token on your mobile device. For RADIUS resources, available authentication methods include Approve/Deny authentication.
In this example, we illustrate the use of the Approve/Deny authentication method.
Launch VMware Horizon Client.
Connect to Horizon Connection Server external FQDN.
Enter your Mirket username and your password.
Input your password in the Password field.
Click on Login. Then, select the 'Approve' option(found in the Mirket mobile app) immediately and make sure it doesn't time out.
