Info

v Do not mark any certificate in the keyfile database as ″default″. v Control the WebSEAL server-side certificate response with the webseal-cert-keyfile-label parameter. v Control the WebSEAL client-side certificate response through the –K junction option. Handling domain cookies The allow-backend-domain-cookies parameter in the [session] stanza of the WebSEAL configuration file allows you to control how WebSEAL handles domain attributes in cookie headers. When this parameter is set to ″no″ (default), WebSEAL performs ″tail matching″ to determine if the domain (contained as an attribute in the cookie header) is valid. If the domain in the cookie header is valid, the cookie is sent to the browser with the domain attribute removed from the cookie header. When a browser receives a cookie with no domain attribute, it can return the cookie only to the originating server. If ″tail matching″ determines that the domain in the cookie header is not valid, the cookie is not sent to the browser. The browser has no cookies to return. [session] allow-backend-domain-cookies = no When this parameter is set to ″yes″, WebSEAL does not perform ″tail matching″ and allows all cookies, regardless of the domain attribute value, to be sent to the browser. The browser can return the cookies to the appropriate server or servers. [session] allow-backend-domain-cookies = yes WebSEAL returns HTTP/1.1 HTTP/1.0 requests are sent to junctioned back-end servers only if those servers return a status of 400 (Bad Request), return a status of 504 (HTTP version not supported), of if the client browser specifies HTTP/1.0 in the request. Otherwise, if the back-end server accepts HTTP/1.1, WebSEAL sends HTTP/1.1 requests. However, even when WebSEAL sends an HTTP/1.0 request to a junctioned back-end server (and the back-end server returns an HTTP/1.0 response), WebSEAL always returns an HTTP/1.1 response to the client browser. Junctioned application with Web Portal Manager Problem: Web Portal Manager sends absolute or server-relative URLs in its Javascript. These addresses are not resolved successfully by the browser and require junction cookie information to complete the path name. Solution: If an application server with Web Portal Manager is junctioned to WebSEAL, you must use the –j option when creating this junction. The junction cookie provided by the –j option allows the browser (client) to successfully issue commands to Web Portal Manager. In addition to using the –j option, you must also use the –c iv_user,iv_creds option. 308 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Using query_contents with third-party servers If you want to protect the resources of the third-party application Web space using the Tivoli Access Manager security service, you must provide WebSEAL with information about the contents of the third-party Web space. A CGI program called query_contents provides this information. The query_contents program searches the third-party Web space contents and provides this inventory information to the Web Portal Manager on WebSEAL. The program comes with the WebSEAL installation, but must be manually installed on the third-party server. There are different program file types available, depending on whether the third-party server is running UNIX or Windows. The Object Space manager of the Web Portal Manager automatically runs query_contents any time the portion of the Protected Object Space representing the junction is expanded in the Object Space management panel. Now that the Web Portal Manager knows about the contents of the third-party application space, you can display this information and apply policy templates to appropriate objects. Installing query_contents components Installing query_contents is typically very easy. Installation involves copying one or two files from the Tivoli Access Manager server to the third-party server and editing a configuration file. The following Tivoli Access Manager directory contains a template of the program: UNIX: install-path/www/lib/query_contents Windows: install-path\www\lib\query_contents The contents of the directory includes: File Description query_contents.exe Main executable program for Win32 systems. Should be installed in the cgi-bin directory of the third-party Web server. query_contents.sh Main executable program for UNIX systems. Should be installed in the cgi-bin directory of the third-party Web server. query_contents.c Source code. The source is provided in case you need to modify the behavior of query_contents. In most cases, this will not be necessary. query_contents.html Help file in HTML format. query_contents.cfg A sample configuration file that identifies the document root for the Web server. Installing query_contents on third-party UNIX servers Locate the shell script named query_contents.sh in the following directory: install-path/www/lib/query_contents Chapter 10. WebSEAL junctions 309
