Info

Typical output looks like: 100 index.html cgi-bin// pics// The number 100 is a return status that indicates success. Customizing the doc root directory UNIX: To customize query_contents.sh for your UNIX server, you might need to modify the document root directory setting. If query_contents returns an error status (a number other than 100) and lists no files, examine the script and modify the $DOCROOTDIR variable, if needed, to match your server’s configuration. If the document root directory is specified correctly and the script still fails, the cgi-bin location specification might be incorrect. Examine the $FULLOBJPATH variable and modify the value assigned to it to reflect the correct cgi-bin location. Windows: To customize query_contents.exe for your Windows server, modify the query_contents.cfg file. Additional functionality The source code for the query_contents program (query_contents.c) is distributed royalty-free with Tivoli Access Manager. Additional functionality can be added to this program to support special features of some third-party Web servers. These features include: v Directory mapping — where a sub-directory not below the document root is mapped into the Web space. v Generation of a Web space that is not file system based. This might be the case for a database-hosted Web server. Securing query_contents The query_contents CGI program is used by Tivoli Access Manager to display junctioned Web server object spaces in the Web Portal Manager. It is very important to secure this file to prevent unauthorized users from running it. You must set a security policy that allows only the policy server (pdmgrd) identity to have access to the query_contents program. The following example ACL (query_contents_acl) meets this criteria: group ivmgrd-servers Tl user sec_master dbxTrlcam Use the pdadmin utility to attach this ACL to the query_contents.sh (UNIX) or query_contents.exe (Windows) object on the junctioned servers. For example (UNIX): pdadmin> acl attach /WebSEAL/host/junction-name/query_contents.sh \ query_contents_acl 312 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Troubleshooting v Problem: query_contents does not work with -b ignore option on junctions. Explanation: If WebSEAL and the Microsoft IIS Web plug-in are both configured and both use basic authentication, then a junction created in WebSEAL to IIS with the -b ignore option specified might not be treated correctly in Web Portal Manager or by the pdadmin command. This problem manifests itself in Web Portal Manager by the object space branch not being expanded for the WebSEAL junction because the query_contents.exe command does not return any information. Similarly, the pdadmin object list /WebSEAL/host_name/junction_name command might not display information on the junction. Workaround: To avoid this problem, temporarily turn off basic authentication on the backend server when the administrators need to apply URI-level access control. Alternately, ensure that the query_contents.exe command is run from a directory that does not require basic authentication. Chapter 10. WebSEAL junctions 313
