IBM DB2 Web Query for i is a replacement for the venerable Query/400 utility. It is used for generating business reports from data stored in DB2 databases on IBM i. It sports a browser-based interface and can generate formatted and interactive reports in multiple formats including spreadsheet, PDF, and HTML.
Until very recently DB2 Web Query did not support SSO via the Kerberos authentication protocol. Many IBM i interfaces support the Kerberos protocol, including telnet server, Client Access host servers (which includes several different interfaces include iNavigator for Windows), ODBC, Apache Web server, Netserver, FTP client, and others. So the lack of Kerberos support in DB2 Web Query was noticeable and frustrating.
