Node Configuration for Hosting Your Web Application on SystemLink Server

When you host your web application on SystemLink Server, leave the server url, username, and password inputs of the Open Configuration (User) node empty. To minimize security vulnerabilities, SystemLink Server will use your LDAP or Windows user account credentials for authentication.
