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, LDAP, or IPA configured on TrueNAS but not multiple directory services simultaneously.
To configure TrueNAS to use an LDAP directory server:
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.
