Question about Subdomain Delegation

To put it simply, MAIN delegates lab both to itself and BSN.

But MAIN does not have authority over lab, since it is not listed
as a zone in its named.conf file.

Fix that by including a proper zone defionition for lab into main's 
named.conf, and I venture to guess your problem will go away.
