Configuring START_TLS LDAP Settings in FreeNAS 11.3

FreeNAS 11.3 had some major changes to the way that it communicates and authenticates with LDAP over secure channels. The base service in FreeNAS 11.3 that handles LDAP Authentication is nslcd, compared to 11.2’s service of sssd.Ìý

FreeNAS 11.3’s nslcd service stores the CA in the /etc/ssl/truenas_cacerts.pem file which is used to encrypt over START_TLS. You can check the configuration for LDAP in the /usr/local/etc/nslcd.conf file.Ìý

To configure advanced LDAP settings in FreeNAS 11.3:

1. Log in to the FreeNAS Administrator Dashboard.
2. Go to Directory Service > LDAP.
3. Click Advanced Mode.
4. Set Encryption Mode to START_TLS.
5. Check Validate Certificates.
6. For Certificate, leave blank (nslcd will use the CA you created in Importing a Certificate in FreeNAS, which is stored in /etc/ssl/truenas_cacerts.pem).
7. Check the Samba Schema option.
8. Click the Save button to complete the LDAP and LDAP Advanced Configurations.

Optional settings for logging: 

1. You can move logging for nslcd to its own file for troubleshooting using the Auxiliary Parameters field in the LDAP configuration in the UI.Ìý
2. Add the following line to create a specific log file under /var/log for nslcd using debug level logging: log /var/log/nslcd.log debug.
