Info

lcp_uri URI encoded local code page data Any UTF-8 characters which can not be converted to local code page will be converted to question marks ( ? ). Use this option with caution and only in environments where local code page produces the desired strings. lcp_bin Un-encoded local code page data. This mode was used by versions of WebSEAL prior to Version 5.1. Use of this mode enables migration from previous versions, and is used in upgrade environments. Use with caution, because data loss can potentially occur with this mode. For more information on WebSEAL support for UTF-8 encoding, see “Multi-locale support with UTF-8” on page 44 306 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Technical notes for using WebSEAL junctions v “Mounting multiple servers at the same junction” on page 307 v “Exceptions to enforcing permissions across junctions” on page 307 v “Certificate authentication across junctions” on page 307 v “Handling domain cookies” on page 308 Mounting multiple servers at the same junction You can mount multiple replicated servers at the same junction point. There can be any number of servers mounted at the same point. All servers mounted at one junction point must be replicas (mirrored Web spaces), and must use the same protocol—HTTP or HTTPS. Do not mount dissimilar servers on the same junction point. From the primary Tivoli Access Manager server Web space, access pages belonging to the junctioned servers. You should be able to access these pages (subject to permissions, of course) and the pages should appear consistent. If a page cannot be found occasionally, or if it changes occasionally, it means that page was not replicated properly. Check that the document exists and is identical in the document tree of both replicated servers. Exceptions to enforcing permissions across junctions Certain Tivoli Access Manager permissions are not enforceable across a junction. You cannot control, for example, the execution of a CGI script with the x permission, or a directory listing with the l permission. WebSEAL has no means of accurately determining whether or not a requested object on a back-end server is, for example, a CGI program file, a dynamic directory listing, or a regular HTTP object. Access to objects across junctions, including CGI programs and directory listings, is controlled only through the r permission. Certificate authentication across junctions At installation, WebSEAL is configured with a non-default test certificate. The test certificate is designated as the active server-side certificate by the webseal-cert-keyfile-label parameter in the [ssl] stanza of the WebSEAL configuration file. If a junctioned back-end application server requires WebSEAL to identify itself with a client-side certificate, you must first create, install, and label this certificate using the iKeyman utility. Then, configure the junction using the –K key-label option. See “Mutually authenticated SSL junctions” on page 282. If the junction is not configured with –K, GSKit handles a request for mutual authentication by automatically sending the “default” certificate contained in the keyfile database. If this is not the required response, you must ensure that there are no certificates marked as ″default″ (an asterisk mark) in the keyfile database (pdsrv.kdb). In summary: v Identify all required certificates by label name. Chapter 10. WebSEAL junctions 307
