FIX: Syntax error - missing fi in extract_user_from_path function

Line 1493 had ';;' instead of 'fi' to close the if statement in the default
case of the extract_user_from_path function. This caused syntax errors.

Changed:
            ;;
    esac

To:
            fi
            ;;
    esac

Script syntax now verified OK.
