the configure script checks for openldap and friends and we link with those libs just like we link all other third party libraries, and we no longer dlopen() those libraries. Our private header file lib/ldap.h was renamed to lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix) just before this commit, just in case.
