How to Enable Active Directory Sync

Enable Active Directory Sync

If you have Active Directory located on your premises, you can use Proofpoint Essentials Active Directory Sync option to add and automatically sync user accounts and groups between environments.

Before you begin, you will need the following:

  1. An inbound connection that allows Proofpoint Essentials IP range to connect to your domain controller
  2. A user account with read permissions to Active Directory
  3. A user account with administrator privileges to Proofpoint Essentials
  4. The Base DN (Distinguished Name)
    • The Base DN is the starting point for directory server searches
    • For example: DC=mycompany,DC=com, the Connector starts from this DN to create the list of users and groups to sync

 

Support for LDAP and LDAP over SSL

The standard protocol for reading data to Active Directory is LDAP. LDAP traffic is unsecured by default. To make LDAP traffic secure, you can use the Secure Sockets Layer/Transport Layer Security (SSL/TLS) protocols. This combination is referred to as LDAP over SSL -- or LDAPS.

To setup your domain controller to accept LDAP over SSL, please refer to the following Microsoft article: How to enable LDAP over SSL
