5.5.2 Connecting NAS to an LDAP Directory
LDAP stands for Lightweight Directory Access Protocol. It is a directory that can store
the information of all the users and groups in a centralized server. Using LDAP, the
administrator can manage the users in the LDAP directory and allow the users to connect
to multiple NAS servers with the same username and password.
This feature is intended for administrator and users who have some knowledge about
Linux servers, LDAP servers, and Samba. An LDAP server which is up and running is
required when using the LDAP feature of the QNAP NAS.
Required information/settings:
The LDAP server connection and authentication information
The LDAP structure, where the users and groups are stored
The LDAP server security settings
Follow the steps below to connect the QNAP NAS to an LDAP directory.
1. Login the web interface of the NAS as an administrator.
2. Go to “Privilege Settings” > “Domain Security”. By default, the option “No domain
security” is enabled. That means only the local NAS users can connect to the NAS.
3. Select “LDAP authentication” and complete the settings.
