摘要： The present invention relates to a device, a method and a central server for providing service to a Lightweight Directory Access Protocol LDAP client from a central server with multiple back-ends. A LDAP request for accessing a service is received from the LDAP client, and the requested service is identified from the LDAP request. One or more back-ends are scheduled to provide service according to a rule predefined for the requested service, which rule indicating which back-end(s) are to be used for the requested service. The scheduled back-end(s) are queried with respective back-end requests according to the rule to obtain back-end responses. A LDAP response based on the obtained back-end responses is formed and is provide to the LDAP client. This allows a central server with multiple back-ends to provide services for LDAP client in a more efficient way.
