Set up the LastPass Active Directory Connector

The Active Directory Connector (AD Connector) is a desktop application that receives Active Directory user updates and automatically makes the same changes in your LastPass Business account.

This article contains the system requirements, installation steps; configuring the connection, actions, sync, proxy, debug, and migration settings.

If desired, you can set up Active Directory Federation Services (AD FS) in your LastPass Business to allow your users to utilize their Active Directory credentials when logging in to LastPass.

System requirements

To install the Active Directory Connector, your local environment must meet the following minimum requirements.

Note:  System requirements may vary depending on your Active Directory environment.
Processor Intel Core Duo
Operating System
  • Windows 8.1 (x64) or later
  • Server 2012 R2 (x64) or later
Important: Operating system must have .NET Framework 4.5.2 or later installed
Memory 8 GB of RAM
Disk Space 500 MB or more
Bandwidth Consumes at least 200 Mbps or more per day
Software LastPass Active Directory Connector desktop app

Configure proxy settings

Proxy settings can be configured per executable, for all .NET apps, or per user by using IE settings. The UI can use Kerberos authentication with the credentials of the currently logged in user (must be a domain user), the service with the credentials of the machine (must be connected to the domain). It’s not enough to change the settings for just the currently logged in user, because only the AD Connector runs as the currently logged in user and the sync service runs as NT AUTHORITY\SYSTEM.
