3.3.2 Specify the user name and password for connecting to SQL Server
By default, Exult attempts to use Windows Authentication to connect to the specified SQL Server database. This means connecting to SQL Server as the user account using Exult. If this is not acceptable, or your database is configured for SQL Server Authentication, you can specify a username and password using the -u <Username> and -p <Password> options. The following example attempts to connect to SQL Server running on host.com using the username BillyJones and password secret.
Exultcmd.exe -u BillyJones -p secret host.com ..
