Single Sign On Authentication

This procedure is approved for Windows Server 2012, Windows Server 2008 and Windows Server 2016.

The BLOCKBIT UTM SSO agent does not need to be distributed among Windows domain devices (workstations). It is an agent that needs to be made available only on the Windows server that owns the domain controller and maintains the AD (Active Directory) on your network, with the role of integrating and synchronizing users.

The SSO client acts integrated with AD login events. Therefore, any device that logs into AD will have its session authenticated at UTM, this includes other operating systems that somehow join AD.

Windows Management Instrumentation - WMI (Agentless Authentication)

Windows Management Instrument (WMI), consists into specifications for devices and applications management consolidation in Windows Server corporate networks.

These specifications are factory set in the W10, W8, Millenium, 2000, XP and Server 2003, 2012, 2016 and 2019 Windows versions. For previous systems, like Windows 98 and NT 4.0 it can be downloaded and installed. 


In the Blockbit UTM, the WMI service is similar to the SSO Agent, however IT IS NOT necessary to install the Agent in the AD (Active Directory).

It's necessary to enable the checkbox in the authentication screen - servers - Windows, "WMI Authentication", and insert the timeout right bellow, that is the time within which the UTM will check the user's sessions with the AD (Active Directory).

Note: The WMI service works only in the Windows authentication method. 

Timeout data:

Default timeout: 15 seconds
Minimum timeout: 10 seconds
Maximum timeout: 600 seconds

WMI - Checkbox and Timeout field

The AD's manager users are set from default with all of the necessary permissions for the WMI to work. In case it's necessary to allow another user who's not a manager, for the WMI to work, follow the steps bellow:

1. In the target server, go to Administrative Tools > Computer Management.

WMI - Settings

2. Expand Services and Applications.

3. Right-click in WMI control and select properties. 

WMI - Properties

4. In the WMI control properties window, select the Securuty tab.
5. Click security.

6. Click "Add" in case of adding a user like a monitor.

WMI - Remote Enable

7. Mark "Remote Enable" for the user or group of users that requires the WMI data.
8. Check if the connection has been successfuly done.

Requirements for running the SSO agent

For the BLOCKBIT SSO agent to work and integrate with the scheduling and login event service, the system requires the installation of the .NET Framework version 3.5 application on the Windows server.

To install .NET version 3.5, use the installation features available in the “Server Manager” panel, item [Add roles and features] of your Windows server.

Download the SSO agent file from your network's Windows AD server and save it to a local directory.

In BLOCKBIT UTM access the Windows Server Menu
