The nodename option is used in two ways:

1.(The original usage) If the nodename is entered either on the
command line or in the dsm.opt file it allows workstationA to
pretend to be workstationB.  This will prompt the user for
the password, irrespective of the PASSWORDACCESS option.

2.The ADSM client's name is (usually) the hostname on the workstation.
This, however, is uppercased when sent to the ADSM server and
'sunxyz' client is the same as 'SUNxyz'.  The nodename option
in the dsm.sys file can be used to override the usage of the hostname.
Passwordaccess option works as if the hostname were used.
