you need to ensure that the FreeRADIUS LDAP module can talk to your
LDAP server - check the LDAP configuration in FreeRADIUS to ensure that
the configuration, password etc etc is fine  (modules/ldap in FR 2.x)

then, enabled the ldap section in the required part of your configuration -
ie you want to authenticate users or authorise them via ldap? uncomment
the required line in eg inner-server (if using EAP) or default otherwise.
the config file supplied by default should be fairly verbose - i cant say 
what the version you get after the pakcage maintainer has done their work on
it - but , if in doubt, download the source tarball from
and check the default contents of the raddb directory!

finally, run in full debug mode

radiusd -X

and sniff/lof the LDAP server to ensure things are doing what you expect
