You can use LDAP authentication against Windows Active Directory by configuring a System Security Services Daemon (SSSD) in the Linux virtual machine.

Use the following high-level steps to implement the SSSD LDAP authentication solution.

Note: To perform an instant-clone offline domain join, you must use one of the supported authentication methods: PowerBroker Identity Services Open (PBISO) authentication or Samba offline domain join. The SSSD LDAP authentication solution is not supported.


  1. To enable LDAPS (Lightweight Directory Access Protocol Over Secure Socket Layer), install the Certificate Services on the Active Directory server.
  2. To use LDAP authentication directly against the Microsoft Active Directory, configure the SSSD in the Linux virtual machine.
