Configuring Freeradius with Ldap Windows Server 2003

Hi, How configuring freeradius with ldap windows server 2003 ? I do in my freeradius, when I installed it is ./configure --prefix=/usr/local/freeradius --with-modules="rlm-ldap" Until I'm configured in radiusd.conf It's Still radiusd.conf[744] Failed to link to module 'rlm_ldap': rlm_ldap.so: cannot open shared object file: No such file or directory radiusd.conf[1956] Unknown module "ldap". radiusd.conf[1956] Failed to parse "ldap" entry. I'm confused now...
