    • Product description

    The IBM Directory Server Client SDK provides the tools required to develop LDAP applications, including the following:

    The sample programs are provided in the following locations:

    Included with the samples is a makefile for use with the sample programs, as well as a sample LDIF file.

    The LDAP C libraries enable the programmer to develop applications that can access an LDAP-compliant Directory Server, including, but not limited to the following:

    The LDAP API provides typical Directory Server functions such as read, write and search. The client can authenticate itself to the Directory Server using a password and Distinguished Name (DN) (simple) or one of the Simple Authentication and Security Layer (SASL) mechanisms (CRAM-MD5, GSSAPI or EXTERNAL).

    C applications

    The client SDK includes tools to build your own LDAP application (LDAP Version 2 or LDAP Version 3). Note that the client SDK for C also provides support for Secure Sockets Layer (SSL), which provides data confidentiality (encryption) on connections protected by SSL. SSL support is enabled when the IBM Global Security Kit, Version 6.0.3 (GSKit) is installed. GSKit is optional software that is included with the IBM Directory Server package.

    Note:
    See Considerations for secure LDAP (using SSL) for important details regarding the use of SSL with Version 5.1 of the IBM Directory Server Client SDK.

    Online documentation

    In addition to the Readme file, online documents including the Administration Guide and the Programming Reference are provided in PDF and HTML format.

    The IBM Directory Server Version 5.1 supports the use of the JNDI client from Sun Microsystems. For information about the JNDI client, go to the Sun Microsystems Web site at http://java.sun.com/products/jndi/1.2/javadoc/index.html

    Considerations for secure LDAP (using SSL)

    Version 5.1 of the IBM Client SDK requires that GSKit 6.0.3 be installed for SSL support. The LDAP libraries and utilities provided with the client SDK use the SSL libraries, if present. The SSL libraries are provided as part of the IBM GSKit 6.0.3. If GSKit has been installed, the LDAP library dynamically loads the SSL libraries and uses them to enable support for SSL. If GSKit has not been installed and the SSL libraries are not available, the LDAP library is fully functional with the exception of SSL support.

    By using SSL with server authentication, an LDAP application can use simple LDAP authentication (user ID and password) over a secure, encrypted communication connection. SSL thus provides for the establishment of a secure connection between the LDAP client application and the LDAP server. In addition, SSL provides data confidentiality (encryption) on connections protected by SSL. Authentication of servers to the clients is accomplished with X.509 certificates.

    Note:
    The IBM Directory Server server component also uses GSKit to enable support for SSL.

    See the IBM Directory Server Version 5.1 C-Client SDK Programming Reference and the IBM Directory Server Version 5.1 Installation and Configuration Guide for information about GSKit.

      where xxx is a specific language identifier.The order in which the packages are listed is crucial. If package dependencies are not met, the installation fails.

    Installing the Linux client

    Note:
    Before installing the IBM Directory Server, you must remove any non-IBM versions of LDAP that might have been installed previously. If you try to install the IBM Directory Server over an existing non-IBM version of LDAP, such as OpenLDAP, the IBM Directory Server does not install correctly. If this occurs you must remove the IBM Directory Server and then reinstall it.

    One method to determine if you have a previously installed version of LDAP is to issue the following command to query the installed packages: 

    rpm -qa | grep -i ldap

    This command finds any installed applications containing the name ldap. This method works only if you have a version of LDAP that contains the string ldap in its application names.

    You can use the InstallShield GUI on all Linux platforms except Linux for S/390 and UnitedLinux.

    The IBM Directory Server client for Linux operating systems is provided in the following packages:

    Intel-based Linux packages:
