Using the switch -enable-ldap instead of –with-ldap did the job for me. (apache httpd 2.2.13 on openSuse 10.3)

There is a configuration difference for Apache 2.2.11 on CentOS 5.2

./configure –enable-deflate –enable-mime-magic –enable-expires –enable-usertrack –enable-unique-id –enable-ssl –enable-http –enable-mod-info –enable-info –enable-cgi –enable-cgid –enable-spelling –enable-module=all –enable-ldap –enable-authnz-ldap –with-ldap –with-included-apr

The “–with-included-apr” and “–with-ldap” are necessary otherwise it won’t compile and keeps giving the same error.

I’m pretty sure that the error message refers to the protocol “LDAP”, version 3. Not a particular implementation of the protocol, such as OpenLDAP. If you are using OpenLDAP, then it supports LDAPv3.

If you are getting the same message after OpenLDAP is installed, “Support for LDAP v2.0…”, then you probably have some old libraries on your system, and it’s using those instead of the new ones from OpenLDAP.

I just noticed in your original post that this is happening in the apr-util folder. Did you build ‘apr’ first, as per the article? It compiled cleanly?

it’s not clear where to find LDAP toolkit 3.0.
The latest available from OpenLdap is 2.4
Apache 2.2.11 fails with it!

I’d say that this is your main problem:

/work/run4/httpd-2.2.11/srclib/apr-util/include/apr_ldap.h:132:2: #error Support for LDAP v2.0 toolkits has been removed from apr-util. Please use an LDAP v3.0 toolkit.

It appears that you have some old LDAP libraries installed…

I ran these steps:

cd ../apr-util
make clean
./configure –prefix=/usr/local/apache2 –with-apr=../apr \
–with-ldap-lib=/usr/lib –with-ldap-include=/usr/include \
–with-ldap=ldap
make

I got no error in the configure; however, make return

How to get rid of these errors?

the problem seems to persist through apache 2.2.9 on Solaris.. the solution above works fine with only one correction…

instead of the “–with-ldap” you have to use “–enable-ldap” option. The former is apparrently depricated (though the source code comments suggest using the old argument)

I believe it is because apr and apr-util don’t get compiled with the –with-ldap option, even when you add it to the top-level apache configure script. A Makefile error is my guess.

Did you run ‘make clean’ in the srclib/apr and apr-util subdirectories before running ./configure and make in those dirs? Where in the build process are you encountering problems, and what is the compile-time error?

Don’t suppose you have any knowledge as to what might have caused that “hiccough” that you experienced when dealing with version 2.0.5.8 where you had to do a reconfigure/remake?

I’ve been trying to get this authz_ldap module to compile on both 2.2.3 and 2.2 with no success whatsoever, even applying your great steps.
