Check your naming
If your users will only access the External Applications via the Workbench, then you do not have to worry about what name you choose when setting up the configuration. However, if they plan to use the clcserver program, from the CLC Command Line Tools, to interact with your CLC Science Server, then please ensure that you do not use the same name as any of the internal commands available. You can get a list of these by running the clcserver command, with your CLC Science Server details, and using the flag with no argument.
Example:
/clcserver -S localhost -P 7777 - U root - W default
<host> <port> <username> <password>
