&reftitle.install; LDAP support in PHP is not enabled by default. You will need to use the --with-ldap[=DIR] configuration option when compiling PHP to enable LDAP support. DIR is the LDAP base install directory. To enable SASL support, be sure --with-ldap-sasl[=DIR] is used, and that sasl.h exists on the system. &ext.windows.path.dll; libeay32.dll and ssleay32.dll Versions before PHP 4.3.0 additionally require libsasl.dll. In order to use Oracle LDAP libraries, proper Oracle environment has to be set.
