[ecsso-incoming-attributes] my_special_attr1 = preserve my_special_attr_* = refresh Using the examples shown above in “Specify extended attributes to add to token” on page 272, the entries in the WebSEAL configuration file for a server that operates in the example2.com domain could be: [ecsso-incoming-attributes] job_category = preserve my_cdas_attr_1 = preserve my_cdas_attr_* = refresh In this example, the attributes job_category and my_cdas_attr_1 are extracted from the token. The remainder of the attributes with the prefix my_cdas_attr_ are ignored. 274 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Chapter 10. WebSEAL junctions A WebSEAL junction is an HTTP or HTTPS connection between a front-end WebSEAL server and a back-end Web application server. Junctions logically combine the Web space of the back-end server with the Web space of the WebSEAL server, resulting in a unified view of the entire Web object space. A junction allows WebSEAL to provide protective services on behalf of the back-end server. WebSEAL performs authentication and authorization checks on all requests for resources before passing those requests across a junction to the back-end server. Junctions also allow a variety of single sign-on solutions between a client and the junctioned back-end application. You can create WebSEAL junctions with the pdadmin command-line utility or with the Web Portal Manager. This chapter discusses the details of the many options for configuring WebSEAL junctions.
