I'm trying to install mod_auth_ldap on Apache running on Solaris 10.
The module builds/installs just fine (after much fighting!) -- but I
get this error from 'apachectl configtest' when I try to start apache:

Syntax error on line 257 of /etc/apache/httpd.conf:
Cannot load /usr/apache/libexec/auth_ldap.so into server: ld.so.1:
httpd: fatal: relocation error: file /usr/apache/libexec/auth_ldap.so:
symbol ldap_unbind_s: referenced symbol not found

I installed the openldap package from sunfreeware into /usr/local; and
configured the module before making it with:

../configure --with-ldap-sdk=openldap --with-sdk-libs=/usr/local/lib --
with-activate --with-sdk-headers=/usr/local/include

? What do I need to link with to fix this missing symbol?

Which indicates that you are trying to use a module that Apache org
states:
Compatibility: Available in version 2.0.41 and later
on Apache 1.3 ??
See: http://httpd.apache.org/docs/2.0/mod/mod_auth_ldap.html

That could be a mistake too. Unless you read the fine print at
sunfreeware you may be missing dependencies.

Is that all? No LDFLAGS?

man ldd - ldd will tell you what cannot be linked. Usually.
But it looks like you are barking up a wrong tree anyway.
Do you really work for Sun?
