Specifying multiple users and/or shares

If you wish to define multiple users and/or multiple shares, use the command statement. Note, you should only provide one command statement.

Correct example:

command: '-u "myuser;mypassword" -s "ShareName;/path/in/container;yes;no;no;myuser"'

Incorrect:

command:
  - '-u "myuser;mypassword"`
  - '-s "ShareName;/path/in/container;yes;no;no;myuser"'
