Troubleshooting NetScaler

By: Raghu Varma Tirumalaraju

Overview of this book

NetScaler is a high performance Application Delivery Controller (ADC). Making the most of it requires knowledge that straddles the application and networking worlds. As an ADC owner you will also likely be the first person to be solicited when your business applications fail. You will need to be quick in identifying if the problem is with the application, the server, the network, or NetScaler itself. This book provides you with the vital troubleshooting knowledge needed to act fast when issues happen. It gives you a thorough understanding of the NetScaler layout, how it integrates with the network, and what issues to expect when working with the traffic management, authentication, NetScaler Gateway and application firewall features. We will also look at what information to seek out in the logs, how to use tracing, and explore utilities that exist on NetScaler to help you find the root cause of your issues.

Form-based Authentication


Form-based authentication is suited to applications that present a login form instead of a dialog box. This sort of authentication configuration makes sense when the application itself is form-based.

Form-based Authentication makes most sense when used with SSO. The typical configuration uses a SuccessRule parameter, which is a means for NetScaler to detect if the SSO was successful or not. If the SuccessRule criterion is met, NetScaler presents the final page, such the User's mailbox, when the application is OWA. If it is not met, NetScaler passes the login page as is to the User so that they can manually enter the credentials – say, when the credentials for SSO are not the same as for NetScaler authentication.

Please take a look at CTX128197 (http://support.citrix.com/article/CTX128197) for an article which shows you how to configure form-based SSO for exchange 2010 through NetScaler.
