SYMPTOM:
The error message `Incorrect login / password` appears when trying to run Strategy Command Manager 10.x from the command line on a non-Windows Operating System.

The same username / password works fine when using the GUI version of Strategy Command Manager 10.x.
CAUSE:
One possible cause for this issue is that the dollar sign, “$”, symbol is used in either the username or the password.
ACTION:
Use single quotes to encapsulate the username and/or password when specified on the command line.
