Agent Installation Compared to Agent Configuration

The concepts of installation and configuration have specific meanings when used to describe CA SiteMinder® agents.

Installation means installing the CA SiteMinder® agent software on a computer system. For example, installing an agent creates directories and copies the CA SiteMinder® agent software and other settings to the computer.

Configuration occurs after installation and means the act of preparing the CA SiteMinder® agent software for a specific web server on a computer. This preparation includes registering the agent with CA SiteMinder® Policy Servers, and creating a runtime server instance for the web server that is installed on the computer.

Use the wizard-based installation and configuration programs to install and configure your agent on your first web server. The wizard-based programs create a .properties file.

Use the .properties file and the respective executable file to install or configure the agent silently on additional web servers.

How to Install Agents on Windows Systems

Installing CA SiteMinder® agents on the Windows operating environment requires several separate procedures. These procedures are described using the following process:

Gather the Information for the Installation Program

Gather the following information about your web server before running the installation program for the CA SiteMinder® agent:

Installation Directory

Specifies the location of the CA SiteMinder® agent binary files on your web server. The web_agent_home variable is set to this location.

Limit: CA SiteMinder® requires the name "webagent" for the bottom directory in the path.

Run the Installation Program on Windows

The installation program for the CA SiteMinder® agent installs the agent on one computer at a time using the Windows operating environment. This installation program can be run in wizard or console modes. The wizard and console-based installation programs also create a .properties file for subsequent installations and configurations using the unattended or silent method with the same settings.

For example, suppose the Agents in your environment use the same web server version, installation directory, Agent Configuration Object and Policy Servers. Use the installation wizard or console-based installation program for your first installation. Afterwards, you could create your own script to run the installation program with the .properties file the wizard or console-based installation program created.

Follow these steps:

Copy the CA SiteMinder® Web Agent installation executable file to a temporary directory on your web server.
Do one of the following steps:
- For wizard-based installations, right-click the installation executable file, and then select Run as Administrator.
- For console-based installations, open a command line window and run the executable as shown in the following example:
```
executable_file_name.exe -i console
```
Use the information that you gathered previously to complete the installation.

How to Configure Agents on Windows Systems

Configuring the agent occurs after the installation. Configuration requires several separate procedures which are described using the following process:

Gather the Information Required by the Configuration Program on Windows

Gather the following information about your CA SiteMinder® environment before running the configuration program for the CA SiteMinder® agent:

Register Host

Indicates whether you want to register a trusted host. This registration creates a trusted host object in the CA SiteMinder® Policy Server and an SmHost.conf file on the web server. The agent uses this information to make an initial connection to CA SiteMinder® Policy Servers when it starts. Register each agent instance as a trusted host only once.

Default:Yes

Limits: Yes, No

Admin User Name

Specifies the name of a CA SiteMinder® user with Administrative privileges that is already defined in the CA SiteMinder® Policy Server. This CA SiteMinder® user account requires privileges to register trusted hosts.

Admin Password

Specifies a password for the Admin User Name that is already defined in the CA SiteMinder® Policy Server.

Confirm Admin Password

Repeats the password entered in the Admin Password field. This value verifies the password for the Admin User Name already defined in the CA SiteMinder® Policy Server.

Trusted Host Object Name

Specifies a unique name for the trusted host you are registering. This trusted host object is stored on the CA SiteMinder® Policy Server.

Host Configuration Object

Specifies the name of a Host Configuration Object that is already defined in the CA SiteMinder® Policy Server. After the agent initially connects to a Policy Server (using the SmHost.conf file settings), subsequent connections use the settings from the Host Configuration Object.

Policy Server IP Address

Specifies the Internet Protocol address of the Policy Servers to which the agent attempts to connect upon startup. If your Policy Server is behind a firewall, specify a port number also.

If a hardware load balancer is configured to expose Policy Servers in your environment through a single Virtual IP Address (VIP), enter the VIP. For more information, see the Policy Server Administration Guide.

Example: (IPV4) 192.168.1.105

Example: (IPV4 with the port number) 192.168.1.105:44443

Example: (IPV6) 2001:DB8::/32

Example: (IPV6) [2001:DB8::/32]:44443

FIPS Mode Setting

Specifies one of the following algorithms:

FIPS Compatibility/AES Compatibility: Uses algorithms existing in previous versions of CA SiteMinder® to encrypt sensitive data and is compatible with previous versions of CA SiteMinder®. If your organization does not require the use of FIPS-compliant algorithms, use this option.
FIPS Migration/AES Migration: Allows a transition from FIPS-compatibility mode to FIPS-only mode. In FIPS-migration mode, CA SiteMinder® environment continues to use existing CA SiteMinder® encryption algorithms as you reencrypt existing sensitive data using FIPS-compliant algorithms.
FIPS Only/AES Only: Uses only FIPS-compliant algorithms to encrypt sensitive data in the CA SiteMinder® environment. This setting does not interoperate with, nor is backwards-compatible with, previous versions of CA SiteMinder®.

Default: FIPS Compatibility/AES Compatibility

Note: FIPS is a US government computer security standard that accredits cryptographic modules which meet the Advanced Encryption Standard (AES).

Important! Use a compatible FIPS/AES mode (or a combination of compatible modes) for both the CA SiteMinder® agent and the CA SiteMinder® Policy Server.

Name

Specifies the name of the SmHost.conf file which contains the settings the Web Agent uses to make initial connections to a CA SiteMinder® Policy Server.

Default: SmHost.conf

Location

Specifies the directory where the SmHost.conf file is stored.

Default: web_agent_home\config

Enable Shared Secret Rollover

Select this check box to change the shared secret that the CA SiteMinder® Policy Server uses to encrypt communications to the Web Agents.

Select Servers

Indicates the web server instances that the configuration program finds on the computer. Select the check boxes of the instances you want to configure. Clear the check boxes of those instances from which you want to remove CA SiteMinder® protection.

Agent Configuration Object Name

Specifies the name of an agent configuration object (ACO) already defined on the Policy Server.

Default: AgentObj

Advanced Authentication Scheme Dialog

Specifies the advanced authentication scheme for the web server instances you selected previously.

Run the Web Agent Configuration Program on Windows

After gathering the information for your agent configuration, run the agent configuration program. This program creates an agent runtime instance for the web servers running on your computer.

This configuration program is wizard or console based, depending on the option you select. Running the configuration program in the wizard or console mode once creates a properties file. Use the properties file to run unattended configurations on other computers with same operating environment in the future.

Follow these steps:

Open the following directory on your web server:
```
web_agent_home\install_config_info
```
web_agent_home

Indicates the directory where the CA SiteMinder® agent is installed on your web server.

Default (Windows 32-bit installations only): C:\Program Files\CA\webagent

Default (Windows 64-bit installations only): C:\Program Files\CA\webagent\win64

Default (Windows 32-bit applications operating on 64-bit systems [Wow64]): C:\Program Files (x86)\webagent\win32
Use one of the following configuration methods:
- For a GUI-based configuration, go to Step 3.
- For a console-based configuration, go to Step 5.
Right-click the following executable, and then select Run as Administrator:
```
ca-wa-config.exe
```
Go to Step 8.
Open a Command Prompt window with Administrator privileges.
Navigate to the executable file listed previously, and then run it with the following switch:
```
-i console
```
Go to Step 8.
Follow the prompts shown in the configuration program. Provide the requested values from your agent configuration worksheet.
The agent runtime instance is created for your web servers.

Run the Unattended or Silent Installation and Configuration Programs for Subsequent Agents on Windows

The unattended or silent installation option can help you automate the installation and configuration process. This method saves time if you have a large CA SiteMinder® environment that uses many agents with identical settings.

Follow these steps:

Run the following wizards on your first web server (in the order shown):
1. The CA SiteMinder® Web Agent Installation wizard.
2. The CA SiteMinder® Web Agent Configuration wizard.
Locate the following file on your first web server:
```
web_agent_home\install_config_info\ca-wa-installer.properties
```
Note: If the path contains spaces, surround it with quotes.

web_agent_home

Indicates the directory where the CA SiteMinder® agent is installed on your web server.

Default (Windows 32-bit installations only): C:\Program Files\CA\webagent

Default (Windows 64-bit installations only): C:\Program Files\CA\webagent\win64

Default (Windows 32-bit applications operating on 64-bit systems [Wow64]): C:\Program Files (x86)\webagent\win32
Perform each of the following steps on the other web servers in your environment:
Note: To automate this process, create your own customized script to execute these files on your systems. Use any scripting language that you want.
1. Create a temporary directory on the subsequent web server.
2. Copy the following files from the first web server (Steps 1 and 2) to the temporary directory on your subsequent web server:
  - The CA SiteMinder® Web Agent Installation executable file.
  - CA SiteMinder® ca-wa-installer properties file.
3. Open a Command Prompt window with Administrative privileges in the temporary directory.
4. Run the following command:
```
agent_executable -f properties_file -i silent
```
  The CA SiteMinder® agent is installed and configured on the subsequent server silently.
5. (Optional) Delete the temporary directory from your subsequent web server.
Repeat Step 3 for each additional web server in your CA SiteMinder® environment that uses the configuration that the settings in your ca-wa-installer.properties file specify.
