Deploying the BIG-IP System with CA SiteMinder

3 Configuring the BIG-IP LTM for the SiteMinder Administrative User Interface servers

Welcome to the F5 deployment guide for CA SiteMinder®. This guide describes how to achieve high availability by deploying the BIG-IP Local Traffic Manager (LTM) with CA SiteMinder, load balancing the Administrative User Interface, the Policy Server and the User Directory Servers.

5 Configuring the BIG–IP LTM for the SiteMinder Policy Servers

Why F5 CA SiteMinder is mission critical to the uptime and availability of entire websites . If SiteMinder is unavailable, so are the web servers that SiteMinder serves. Therefore, high availability and proactive health monitoring is critical to the success of all SiteMinder deployments. Organizations using SiteMinder receive the benefits immediately after deploying the BIG-IP LTM: • H  igh availability of CA SiteMinder Policy Servers at the network layer. Instead of configuring IP Addresses manually in the SiteMinder Configuration files and relying on manual intervention, the BIG-IP system automatically directs users to the most available CA SiteMinder server. • H  igh availability of CA Administrative UI servers. Equally as important as the Policy Servers, if an Administrative server goes down, users are no longer able to maintain, manage or troubleshoot policy servers. Load balancing the Administrative UI is often overlooked, but is extremely important. • W  ith the BIG-IP system, organizations can configure an architecture that solves the many different pieces of a CA Architecture entirely on one platform, the BIG-IP LTM. Specifically, the BIG-IP LTM addresses the high availability needs of Policy Servers, Directory Servers, Administrative Servers, and the content servers themselves.

DEPLOYMENT GUIDE CA SiteMinder

Important: M  ake sure you are using the most recent version of this deployment guide, available at www.f5.com/pdf/deployment-guides/ca-siteminder-dg.pdf

Prerequisites and configuration notes hh The BIG-IP LTM system must be running version 11.2 HF 1 or later. hh E ach SiteMinder Administrative UI server must be registered directly with a SiteMinder Policy server before it is configured for load balancing. Register your Administrative UI servers directly with a policy server instead of using the BIG-IP Virtual IP Address (VIP). After initial registration you may point to the BIG-IP system's virtual server address. See Configuring the SiteMinder devices on page 3.

Configuration example SiteMinder is a critical component of any infrastructure in which it is deployed, so being able to achieve high availability is critical. The BIG-IP system can bring high availability through monitoring to CA SiteMinder environments. The CA SiteMinder environment has several locations where scaling and high availability are critical: • The BIG-IP system is deployed in front of multiple redundant Administrative User Interfaces • The BIG-IP system is deployed in front of multiple redundant Policy Servers • The BIG-IP system is deployed in front of the entitlement and user stores (LDAP) After the deployment of BIG-IP these are the traffic scenarios: 1. A  dministrators use the Administrative UI virtual server on the BIG-IP system to manage and administer CA SiteMinder. This virtual server is typically not externally accessible. 2. A  gents, configured on web servers and application servers, communicate through a virtual server on the BIG-IP system to the Policy Server. This virtual server is also not typically externally accessible. 3. T he Policy Server communicates to a virtual server on the BIG-IP system to reach the LDAP servers.

DEPLOYMENT GUIDE CA SiteMinder

Configuring the BIG-IP LTM for the SiteMinder Administrative User Interface servers The SiteMinder Administrative User Interface must be used to manage and configure the CA SiteMinder environment. If anything happens to the machine running the Administrative User Interface, management of the CA environment becomes difficult and it could lead to a complete site-wide outage. CA recommends the deployment of multiple redundant Administrative User Interface servers. Each Administrative User Interface device must be registered with a Policy server. In the case of multiple identical policy servers, it is important that each Administrative User Interface machine is registered before configuring the BIG-IP system for load balancing.

Configuring the SiteMinder devices Use the following guidance for configuring SiteMinder devices. Refer to the CA documentation for specific instructions. 1. Setup two identical servers and install the CA Administrative User Interface servers 2. Initiate the setup scripts according to CA's instructions and register the Administrative User Interface with the Policy server's direct IP address. 3. Repeat step 2 to register the Policy Server with the other Policy servers in your environments. 4. Configure the BIG-IP LTM system for the Administrative UI servers. 5. Configure the BIG-IP LTM for the Policy Servers. 6. A  djust the IP address on the Administrative User Interface to point to the BIG-IP LTM virtual server IP address for the Policy Servers. Following these steps ensures that each Administrative UI device is properly registered with each Policy Server. If your Administrative UI devices are already registered, these steps can be skipped.

Configuration table for the Administrative User Interface The following table contains a list of BIG-IP LTM configuration objects along with any nondefault settings you should configure as a part of the User Interface configuration. Unless otherwise specified, settings not mentioned in the table can be configured as applicable for your configuration. For specific instructions on configuring individual objects, see the online help or product manuals.

DEPLOYMENT GUIDE CA SiteMinder

Next Steps After completing the BIG-IP LTM configuration, perform the following tasks on your SiteMinder servers. See the SiteMinder documentation for specific instructions. 1. Adjust your SmHosts.conf files on every webAgent to point to the BIG-IP virtual server address for Policy Server. 2. A  djust your Administrative User Interface to point to the appropriate BIG-IP virtual server for Policy Server 3. A  dvertise the BIG-IP virtual server address for the Administrative User Interface so that users can administer CA using this implementation. 4. A  djust the User Directory settings with the CA SiteMinder Configuration to point to the BIG-IP virtual server IP address for the LDAP servers.

Optional: Configuring your directory servers for high availability with BIG-IP We strongly recommend configuring BIG-IP LTM for your directory servers. You can find deployment guides for configuring directory servers on f5.com (http://www.f5.com/products/documentation/deployment-guides/ ). In this section, we show you how to use the BIG-IP LTM iApp template for LDAP servers. For more information on iApps, see http://www.f5.com/pdf/white-papers/f5-iapp-wp.pdf To configure the iApp for LDAP 1. Log on to the BIG-IP system. 2. On the Main tab, expand iApp, and then click Application Services. 3. Click Create. The Template Selection page opens. 4. In the Name box, type a name. In our example, we use SiteMInder_LDAP_. 5. From the Template list, select f5.ldap. The LDAP template opens. 6. Complete the template as appropriate for your LDAP configuration. 7. Click the Finished button. 8. Adjust your policy server to point to the BIG-IP virtual server for your directory servers. For more information on configuring the BIG-IP LTM for LDAP servers, including manual configuration procedures, see http://www.f5.com/pdf/deployment-guides/ldap-iapp-dg.pdf
