Add an authentication profile to specify how HCL SafeLinx authenticates users before it permits access to application servers. SafeLinx supports the following authentication methods: LDAP-bind, RADIUS, and certificate-based.
Using RADIUS servers
You can configure the SafeLinx Server to use and communicate with third-party RADIUS servers.
Configuring the SafeLinx Server to use RADIUS servers for accounting and billing
You can configure a SafeLinx Server to send accounting messages to a RADIUS server.

Administering
This section describes how to plan for, install, configure, operate, and manage the SafeLinx Server.
- Overview
  HCL SafeLinx uses standards-based protocols to enable secure access from mobile computing devices outside the firewall to business applications and data on your organization's internal network.
- Security
  HCL SafeLinx includes a range of options for configuring the security of your network, applications, and data.
- Installation planning
  Before you install HCL SafeLinx, verify that you meet the hardware and software requirements, and that the network connections that you want to use are available.
- Roadmaps: Installing and setting up SafeLinx
  The following "roadmap" topics guide you through installing and initially configuring SafeLinx. Refer to the topic that corresponds to your relational database and server operating system.
- Installing and initial configuration
  Initial configuration and installation of HCL SafeLinx varies based on your operating system and relational database.
- Adding a secure login profile
  By default, the SafeLinx Administrator communicates with the access manager over an unencrypted connection. If you want the connection between the SafeLinx Administrator and the access manager to use transport layer security (TLS) protocols, add a secure login profile to the SafeLinx Administrator.
- Adding and configuring resources
  After you complete the installation and initial configuration, continue to prepare the deployment by configuring other network resources.
  - Types of resources
    Before a deployment can support client connections, you must add components to the SafeLinx Server. You use the SafeLinx Administrator to add and configure components. These components include resources to support HTTP access services, mobile access services, and messaging services, and resources to establish security and facilitate administration.
  - Defining a SafeLinx Server by using the SafeLinx Administrator
    Before you can define a SafeLinx Server, you must configure the access manager. If you connect to a SafeLinx Server and its access manager is not yet configured, a wizard leads you through the access manager configuration first. After that process completes, you can configure the SafeLinx Server.
  - Configuring a directory server
    You can configure the SafeLinx Server to retrieve user profile information from an external LDAP server. The directory server that you configure also provides information about how to contact other directory server services. After you configure a directory server, you can assign it to an LDAP-bind authentication profile to authenticate clients when they log in.
  - Securing communications between the SafeLinx Server and other nodes
    The SafeLinx Server and the services that it hosts exchange data with clients on the external network and with different types of servers on the internal network. To ensure the privacy of these communications, you can use TLS protocols to encrypt connections between the SafeLinx Server and other nodes.
  - Adding HTTP access services
    Add one or more HTTP access services to provide secure access to internal applications for remote users who do not have the full HCL SafeLinx VPN client (SafeLinx Client) installed.
  - Configuring an HCL Nomad server
    You can configure a SafeLinx as an HCL Nomad server that acts as a proxy for HCL Nomad clients.
  - Adding authentication profiles
    Add an authentication profile to specify how HCL SafeLinx authenticates users before it permits access to application servers. SafeLinx supports the following authentication methods: LDAP-bind, RADIUS, and certificate-based.
    - Adding LDAP-bind authentication profiles
      Add an LDAP-bind authentication profile to provide the SafeLinx Server with information about how to connect directly with an LDAP server servers to authenticate users.
    - Using RADIUS servers
      You can configure the SafeLinx Server to use and communicate with third-party RADIUS servers.
      - Creating RADIUS authentication profiles
        You can configure a SafeLinx Server can to connect to a third-party RADIUS server to authenticate users. To enable the use of RADIUS authentication, you create a RADIUS authentication profile.
      - Configuring the SafeLinx Server to use RADIUS servers for accounting and billing
        You can configure a SafeLinx Server to send accounting messages to a RADIUS server.
    - Configuring client certificate authentication for SafeLinx Clients
      You can configure an authentication profile that requires SafeLinx Clients to present X.509 certificates when they log in.
  - Adding a mobile access service
    If there is no mobile access service configured for the SafeLinx Server, you can add one.
  - Adding messaging services
    Add messaging services to the SafeLinx Server to enable applications to send messages to messaging clients, such as a pager or a phone, over mobile wireless networks. Messaging services include support for short message service (SMS) delivery, and mobile-originated message delivery.
  - Adding users
    If your SafeLinx deployment does not use an external LDAP or RADIUS authentication server, use SafeLinx Administrator to create user accounts. You can add users individually or in a batch mode.
- Administering
  The SafeLinx Administrator administration client is the primary tool for viewing, adding, configuring, and managing HCL SafeLinx resources. Along with the SafeLinx Administrator, you can use the HCL SafeLinx Monitor to view information about packet flow through the SafeLinx Server. You can also use a set of command line tools to perform common SafeLinx Server tasks.
- Programming reference
  There are several programming considerations of which you might want to take advantage.
- Database schema information
  HCL SafeLinx uses a DB2, Oracle, MySQL, or SQL database to store tables of information about current and past activity of SafeLinx Server sessions. The following tables are created and accessed by using the qualifier name wg for DB2 installations.
- Step by step: Nomad configuration
  Here are step-by-step instructions that serve as an example of how to install and configure HCL SafeLinx for Nomad on MySQL on Linux.

Configuring the SafeLinx Server to use RADIUS servers for accounting and billing

You can configure a SafeLinx Server to send accounting messages to a RADIUS server.

Before you begin

A RADIUS accounting server must be available to the SafeLinx Server.

About this task

The SafeLinx Server can send accounting packets to a RADIUS server to track the amount of data that users exchange during each session. You can configure the SafeLinx Server to send RADIUS accounting data even if you don't use RADIIUS authentication.

A dictionary file, dictionary.ewg, on the SafeLinx Server lists the accounting attributes and attribute values that the SafeLinx Server sends to the RADIUS server in different packet types. You can view the dictionary file with a text editor. On Linux servers, this file is in /opt/hcl/SafeLinxServer/conf. On Windows servers, it is in C:\Program Files\hcl\SafeLinx Server\conf.

Complete the following procedure to enable the SafeLinx Server to send accounting packets to a RADIUS server.

Procedure

From the SafeLinx Administrator, right-click the SafeLinx Server that you want to configure and then click Properties.
From the RADIUS accounting page, select Use RADIUS accounting.
Specify the IP address and port of the primary RADIUS accounting server.
If you want to configure an alternative RADIUS server to be used if the primary server is unreachable, specify the connection information in the Secondary RADIUS accounting server IP address and Secondary RADIUS accounting server port number fields.
In the RADIUS accounting shared secret field, type the password or shared secret that the SafeLinx Server provides to authenticate with the RADIUS server.
To enable the SafeLinx Server to communicate with both a primary and secondary RADIUS server, the two servers must be configured to use the same shared secret.
