As you suggested, I use the following expressions:
==========================================
qxu at durian(pts/3):/etc[19]$ ldapsearch -Y GSSAPI -H 'ldap://sesswin2003.sesswin2003.com' -b 'dc=sesswin2003,dc=com' -s sub -LLL 'cn=qxu' mail
ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)
==========================================
The domain name is "sesswin2003.com", the host name is "sesswin2003". Thus the FQDN in the expression is "sesswin2003.sesswin2003.com". But the result seems worse. 

Did I miss anything?

Thank you, Doug!
