Hi David,

I'm not an LDAP expert. I suggest now that it seems the compilation worked fine and ldao is in place, you start a new discussion thread about how to use ldap authentication.

Please provide your configuration and th below error messages when starting that discussion.

Regards,

Rainer

Hi Rainer,
I followed those two document and corrected my configuration.
Now http started fine. But when I hit the restricted folder. I still got error.
Here is my error_log, parser fine but ldap initialization failed. How do I test my apache ldap function? Or do I need to recompile my apr-util?

Hi Rainer,
I downloaded apr 1.4.2 and apr-util 1.3.10
For apr 1.4.2, I did "configure --prefix=/www/apache2/apr-httpd/"
For apr util 1.3.10, I did "configure --prefix=/www/apache2/apr-util-httpd/ --with-apr=/www/apache2/apr-httpd/ --with-ldap"

For httpd-2.2.17
configure \
"--prefix=/www/apache2" \
"--with-apr=/www/apache2/apr-httpd/" \
"--with-apr-util=/www/apache2/apr-util-httpd/" \

"--enable-deflate" \
"--enable-rewrite" \
"--enable-headers" \
"--enable-cgid" \
"--enable-ldap" \
"--enable-authnz-ldap" \

All compiled and installed fine.

But I got error when I started http,
# bin/apachectl start
Syntax error on line 115 of /www/apache2/conf/sites-enabled/www.lynden.com.conf:
Invalid command 'LDAP_Server', perhaps misspelled or defined by a module not included in the server configuration

That's true, there is no configuration directive named "LDAP_Server".

I had line like "LDAP_Server 128.1.10.243" in config file.

So that is a configuration error.

See

http://httpd.apache.org/docs/2.2/en/mod/mod_ldap.html

and

http://httpd.apache.org/docs/2.2/en/mod/mod_authnz_ldap.html

I checked "util_ldap.c" is in the httpd -l listing
# /www/apache2/bin/httpd -l
Compiled in modules:
    core.c
    mod_authn_file.c
    mod_authn_default.c
    mod_authz_host.c
    mod_authz_groupfile.c
    mod_authz_user.c
    mod_authnz_ldap.c
    mod_authz_default.c
    mod_auth_basic.c
    mod_include.c
    mod_filter.c
    mod_deflate.c
    util_ldap.c

Correct. This is (unfortunately) the name of mod_ldap when compiled in
statically.

    mod_log_config.c
    mod_env.c
    mod_headers.c
    mod_setenvif.c
    mod_version.c
    mod_proxy.c
    mod_proxy_connect.c
    mod_proxy_ftp.c
    mod_proxy_http.c
    mod_proxy_scgi.c
    mod_proxy_ajp.c
    mod_proxy_balancer.c
    mod_ssl.c
    prefork.c
    http_core.c
    mod_mime.c
    mod_status.c
    mod_autoindex.c
    mod_asis.c
    mod_cgi.c
    mod_cgid.c
    mod_negotiation.c
    mod_dir.c
    mod_actions.c
    mod_userdir.c
    mod_alias.c
    mod_rewrite.c
    mod_so.c

But there is no mod_ldap.so module in apache libexec or modules directories

Check the timestamps of the files in the libexec directoy. I expect all
of them are older than the installation and they do not belong to your
new installation. You compiled the modules staticaly, so they are built
into the httpd binary, not as separate loadable module files. By default
Apache installs all modules into a directory named modules. The name
"libexec" was used long ago only for Apache 1.3 (and older). The modules
below are not for Apache 1.3 but might be left overs from some other
Apche 2.0 installation (e.g. mod_perl and mod_auth_gs do not come
bundled with Apache).

# ls /www/apache2/libexec
httpd.exp             mod_dir.so            mod_proxy.so
mod_access.so         mod_disk_cache.so     mod_proxy_connect.so
mod_actions.so        mod_env.so            mod_proxy_ftp.so
mod_alias.so          mod_expires.so        mod_proxy_http.so
mod_asis.so           mod_ext_filter.so     mod_rewrite.so
mod_auth.so           mod_file_cache.so     mod_setenvif.so
mod_auth_anon.so      mod_headers.so        mod_speling.so
mod_auth_dbm.so       mod_imap.so           mod_ssl.so
mod_auth_digest.so    mod_include.so        mod_status.so
mod_auth_gss.so       mod_info.so           mod_suexec.so
mod_autoindex.so      mod_log_config.so     mod_unique_id.so
mod_cache.so          mod_log_forensic.so   mod_userdir.so
mod_cern_meta.so      mod_mem_cache.so      mod_usertrack.so
mod_cgi.so            mod_mime.so           mod_version.so
mod_dav.so            mod_mime_magic.so     mod_vhost_alias.so
mod_dav_fs.so         mod_negotiation.so
mod_deflate.so        mod_perl.so

Can you or someone tell me what is missing?

I'd say nothing is missing, but your configuration is wrong.

Rainer
