>Description:
	Lighttpd's authn_ldap module links to base libldap.so, not pkgsrc's.
	However, it's built against pkgsrc OpenLDAP.
	The result is the module reporting missing symbols (ldap_destroy, in my case).
	If your base ldap is not much older than your pkgsrc one, the problem may surface so obviously. Probably other Bad Things happen.
>How-To-Repeat:
	ldd /usr/pkg/lib/lighttpd/mod_authn_ldap.so | grep -F libldap
>Fix:
	My hack is to LD_PRELOAD the pkgsrc libldap via lighttpd_env in the rc script.
