Yesterday, my resolve.conf was like this:
=================================
search sgp.fujixerox.com sesswin2003.com
nameserver 13.198.8.83 
nameserver 13.198.96.10 
nameserver 13.198.98.35
=================================
To my dismay, it didn't work. The hostname "sesswin2003" still couldn't be resolved to its IP address.

Today, with the help of our local SA, the file is changed to: 
=================================
search sgp.fujixerox.com sesswin2003.com
nameserver 13.198.98.35
nameserver 13.198.96.10
=================================
It seems the order of nameserver list is important. Quite strange. Or it may be the problem of some DNS server. Because if I put the nameserver 13.198.96.10 in front of 13.198.98.35, it still doesn't work. By right, if a hostname can't be located by the first nameserver, it should continue to look for the hostname in the second nameserver, right?

Anyway, now nslookup works perfectly:
=================================
qxu at durian(pts/1):/etc[17]$ nslookup sesswin2003
Server:         13.198.98.35
Address:        13.198.98.35#53

Name:   sesswin2003.sesswin2003.com
Address: 13.198.98.35

qxu at durian(pts/1):/etc[18]$ nslookup sesswin2003.sesswin2003.com
Server:         13.198.98.35
Address:        13.198.98.35#53

Name:   sesswin2003.sesswin2003.com
Address: 13.198.98.35
=================================
For me, it is quite promising. 

Then I did what Michael and Doug told me, i.e. kinit, klist and ldapsearch: 
=================================
qxu at durian(pts/1):/etc[19]$ kinit qxu at SESSWIN2003.COM
Password for qxu at SESSWIN2003.COM: 

qxu at durian(pts/1):/etc[20]$ klist

=================================
It works perfectly. Next I will use this as a bench against my own coding.

Thanks to all,
