Maintaining the Directory Server
Use
Use the maintenance function of the directory server (transaction LDAP) to configure and maintain the information required for the use of the LDAP Connector:
-
Configure Connection Data for the Directory Service (Configure LDAP Server)
-
Defining the System User of the Directory Service (Configure LDAP User)
In addition, you can monitor the LDAP Connector with the Computing Center Management System (transaction RZ20).
Prerequisites
The LDAP Connector requires access to a specific LDAP library that may not yet be installed on specific application server platforms. You can find a list of the LDAP libraries for all platforms in the SAP Service Marketplace, under:

Check whether the LDAP Connector is operable; that is check the availability of the LDAP library, as follows:
Start the LDAP Connector at operating system level in the kernel directory with the following command: ldap_rfc
The LDAP Connector displays a version number and other technical details. If an error occurs, analyze the operating system error message.
