Info

v It is highly recommended that you also configure the junction for DN matching (–D). You must surround the user name and password arguments with double quotation marks. For example: -U "WS1" -W "abCde" Handling client identity information across junctions A junction can be set up to specify client identity information in BA headers. The –b option allows four possible arguments: filter, supply, ignore, gso. You can find detailed information about these arguments in “Configuring BA headers for single sign-on solutions” on page 316. The –b option has an impact on the junction settings for mutual authentication and you must consider the correct combination of options. Using –b supply v WebSEAL authentication via BA header is not allowed with this option. This option uses the BA header for the original client user name and a ″dummy″ password. v WebSEAL authentication via client certificate is allowed with this option. Using –b ignore v WebSEAL authentication via BA header is not allowed with this option. This option uses the BA header for the original client user name and password. v WebSEAL authentication via client certificate is allowed with this option. Using –b gso v WebSEAL authentication via BA header is not allowed with this option. This option uses the BA header for user name and password information supplied by the GSO server. v WebSEAL authentication via client certificate is allowed with this option. Using –b filter v Internally, the –b filter option is used when WebSEAL authentication is set to use BA header information. The WebSEAL BA header is used for all subsequent HTTP transactions. To the back-end server, WebSEAL appears logged on at all times. v WebSEAL authentication via client certificate is allowed with this option. v If the back-end server requires actual client identity (from the browser), the CGI variables HTTP_IV_USER, HTTP_IV_GROUP, and HTTP_IV_CREDS can be used. For scripts and servlets, use the corresponding Tivoli Access Manager-specific HTTP headers: iv-user, iv-groups, iv-creds. 284 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Creating TCP and SSL proxy junctions You can create WebSEAL junctions that allow communication to traverse network topologies that use HTTP or HTTPS proxy servers. You can configure the junction to handle requests as standard TCP communication or protected SSL communication. The create command requires one of the following arguments to the type option to establish either a TCP-based or SSL-based junction through a proxy server: v –t tcpproxy v –t sslproxy Both create and add commands require the following options and arguments to identify the proxy server and the target Web server: –H host-name The DNS host name or IP address of the proxy server. –P port The TCP port of the proxy server. –h host-name The DNS host name or IP address of the target Web server. –p port The TCP port of target Web server. Default is 80 for TCP junctions; 443 for SSL junctions. Example TCP proxy junction (entered as one line): pdadmin> server task web1-webseald-cruz create -t tcpproxy \ -H clipper -P 8081 -h www.ibm.com -p 80 /ibm Example SSL proxy junction (entered as one line): pdadmin> server task web1-webseald-cruz create -t sslproxy \ -H clipper -P 8081 -h www.ibm.com -p 443 /ibm Client WebSEAL Web Server www.ibm.com Secure Domain -H and -P Proxy Server Clipper Internet -h and -p junction at /ibm Figure 11.
