Thank you all for the suggestions.

I have already installed FreeRadius 2.1.12 which I am running, an I have got
ldap in file /usr/local/etc/raddb/modules/ldap; I have gone through it and I
am still not sure where the problem lies.
 
I have here included below the part of debug mode output that I have got
running radiusd -X. I have illustrated the output part after "Linked to
module rlm_ldap"
