This option specifies the name of the user to be used in connecting to the domain. If user or username is specified, then password must also be specified, as described in “Option to specify the password” on page 45. If the username is not given, then the API refers to the clientConnect.conf file to determine the authentication information to use when establishing the connection.
There is no default username.
There are two different syntaxes that can be used to specify the username:
user => $user_name
username => $user_name
If no username is specified, the script inspects and interprets the SM_AUTHORITY environment variable in the same way that the main SDK software does and may prompt the user for the username and password by using the standard I/O device.
