Quick installation instructions (UNIX): - Building on generic Unix: Add generic ldap support and the TWO ldap modules to the build, like this: ./configure --with-ldap --enable-ldap --enable-authnz-ldap The --with-ldap switches on LDAP library linking in apr-util. Make sure that you have an LDAP client library available such as those from Netscape/iPlanet/Sun One or the OpenLDAP project. The --enable-ldap option switches on the LDAP caching module. This module is a support module for other LDAP modules, and is not useful on its own. This module is required, but caching can be disabled via the configuration directive LDAPCacheEntries. The --enable-auth-ldap option switches on the LDAP authentication module. - Building on AIX: The following ./configure line is reported to work for AIX: CC=cc_r; export CC CPPFLAGS=-qcpluscmt;export CPPFLAGS ./configure --with-mpm=worker --prefix=/usr/local/apache \ --enable-dav=static --enable-dav_fs=static --enable-ssl=static --with-ldap=yes --with-ldap-include=/usr/local/include --with-ldap-lib=/usr/local/lib --enable-ldap=static --enable-authnz-ldap=static Quick installation instructions (win32): 1. copy the file srclib\apr-util\include\apr_ldap.hw to apr_ldap.h 2. the netscape/iplanet ldap libraries are installed in srclib\ldap 3. Compile the two modules util_ldap and mod_authnz_ldap using the dsp files 4. You get a mod_authnz_ldap.so and a mod_ldap.so module 5. Put them in the modules directory, don't forget to copy the nsldap32v50.dll somewhere where httpd.exe will find it 6. Load the two modules in your httpd.conf, like below: LoadModule ldap_module modules/mod_ldap.so LoadModule authnz_ldap_module modules/mod_authnz_ldap.so 7. Configure the directories as described in the docus.
