Ok. Thanks for your kind and early explanation. :)

But let me add to that,

I have,

Cisco 2960 G switch  			as Next AP.
D'Link DIR 600 Wireless Router	as Current AP.

So Is there any configuration pertained to pre-authentication to be done on Next AP. If it is, then how to do that?
Note that, I am not using "hostapd" as an AP. I am using APs mentioned above.

I do not know what you are referring to with "802.1x

Enabling pre-authentication should be enough; the pre-authentication
packets from the supplicant are use their own ethertype and are sent to
the BSSID of the target AP, so as long as bridging is set up correctly
between the APs, that should work transparently at the current AP.
