TrueNAS has an Open LDAP client for accessing the information on an LDAP server. An LDAP server provides directory services for finding network resources like users and their associated permissions.
You can have either Active Directory or LDAP configured on TrueNAS but not both.
To configure TrueNAS to use an LDAP directory server:
Support for LDAP Samba Schema is deprecated in TrueNAS 22.02 (Angelfish) and removed in 24.10 (Electric Eel). Migrate legacy Samba domains to Active Directory before upgrading to 24.10 or later.
The LDAP widget displays after you configure TrueNAS settings for your LDAP instance. The widget includes Status, and the Hostname and Base DN and Bind DN you configured.
TrueNAS provides the option to configure a FreeIPA directory service client using the LDAP configuration screen under Credentials > Directory Services.
You can have either Active Directory or LDAP configured on TrueNAS, but not both.
You must do the following things listed in this section. See the procedure below for detailed steps.
The Directory Services screen and widgets provide access to TrueNAS settings to set up access to directory services and advanced authentication systems deployed in user environments.
TrueNAS does not configure Active Directory domain controllers or LDAP directory servers, nor does it configure Kerberos authentication servers or ID mapping systems.
Refer to documentation for these services and systems for information on how to configure each to suit your use case.
