How does Web Express Logon work?

The overall goal of Web Express Logon is to provide an automated way for users to log on to hosts and host-based applications without having to provide an additional ID and password. In order to accommodate the wide range of supported computing environments, Web Express Logon offers two styles of logon automation:

The style of logon automation that best suits your needs depends on your environment, including your host type, session type, and your current method for authenticating users. If the host does not allow the client to supply the needed credentials at the time the connection is established, for example, if the client must authenticate to the host after the host connection is established, macro-based automation is the appropriate style. In this model, the host must send a login screen to authenticate the client. The macro automates the login screen, populates the screen's credential fields with the appropriate user information, and then transmits this information to the host for authentication. However, if your host allows the client to supply the needed host credentials at the time the host connection is established, for example, using Kerberos authentication or FTP login, connection-based automation is the appropriate style.

The following sections provide more details about macro- and connection-based automation, including high-level overviews of some example environments supported by Web Express Logon. These examples are discussed in more detail throughout the remainder of this document.
