I think this is the problem.  In the three files 

	source/lib/rpc/server/srv_wkssvc.c:create_wks_info_100()
	source/lib/rpc/server/srv_srvsvc.c:srv_reply_net_srv_get_info()
	source/lib/rpc/server/srv_netlog.c:api_net_sam_logon()

There is a call which sets the name returned to be the DNS name.  Since
the DNS name and NetBIOS name are different, this breaks things.  I my
case, I was running a second samba server acting as the PDC.  The login
script would not run because it was trying to get a reponse from the
server on the primary interface.

You can either try changing the NetBIOS name to the DNS name.  Or
comment out the call to get_myname(myname, NULL) in the 3 functions
listed above.  Since myname is a global variable that should already
have the NetBIOS name in it, commenting out these calls should be of no
consequence.  In fact, they probably should not be there at all unless
the myname string is empty.

This has been reported to samba bugs.
