Compilation Decompress the tarball (tar.gz). [root@deep /]# cp openldap-version.tgz /var/tmp [root@deep /]# cd /var/tmp/ [root@deep tmp]# tar xzpf openldap-version.tgz Compile and Optimize Move into the new OpenLDAP directory and type the following commands on your terminal: Step 1 Edit the string.h file (vi +52 include/ac/string.h) and remove the lines: #else /* some systems have strdup(), but fail to declare it */ extern char *(strdup)(); The lines above don’t apply to our Linux system and must be removed for clarity. Step 2 It is important to note that you can configure three different kinds of backend database with LDAP. A high-performance disk-based database named “LDBM”; a database interface to arbitrary UNIX commands or shell scripts named “SHELL”; and a simple password file database named “PASSWD”. The default installation of OpenLDAP assumes an LDBM backend database, so if you want to configure another type of backend database, you must specify it during the configuration and compile time. For a SHELL backend database you must add the “--enable-shell” option and for a PASSWD backend database (used as replacement for NIS service) you must add the “--enable- passwd” option in your configuration lines.
