1. What is LDAP?

LDAP, or Lightweight Directory Access Protocol, is a client-server protocol for managing related information from a centralized location through the use of a file and directory hierarchy. In other words, it is a protocol for accessing a directory service.

LDAP is used as a phone book on Yeastar S-Series PBX, so that you can search a key word from your IP phone. It is an easy and sophisticated solution based on LDAP services available, fulfilling the requirement searching a phone directory quickly. LDAP Server in S-Series provides centralized phone book management, which makes phone book management easy and intuitive. You can set up S-Series VoIP PBX as a server. Once the LDAP is set up, you can search the LDAP directory and look up contacts on your IP phone.

For example, you can search name, email and telephone, such as “Yeastar”, and it will return all the contacts containing Yeastar.

2. Configure LDAP Server on S-Series VoIP PBX

LDAP Server is an App in S-Series VoIP PBX App Center. So you can install, uninstall, and upgrade LDAP Server in App Center. After installing LDAP Server App on S-Series PBX, follow the below instruction.
