8.1 Authentication Issues Authentication is a complex topic, and your existing network infrastructure can affect your ability to successfully perform an initial iManager login. The following facts can help you minimize authentication‐related difficulties. For more information about authentication‐related topics, see the Novell Modular Authentication Service (NMAS) documentation (http://www.novell.com/ documentation/nmas33/index.html) and Novell eDirectory documentation (http://www.novell.com/ documentation/edir88/index.html). • iManager authentication is a platform‐dependent operation, meaning that it functions differently depending on the platform on which iManager is running Linux and Windows servers: When iManager runs on a Linux or Windows server it utilizes eDirectory’s legacy authentication mechanism and the regular eDirectory password. This mechanism supports eDirectory’s Universal Password option but does not support the Simple Password option. iManager Workstation: iManager Workstation runs on a client workstation, either Linux or Windows, and leverages the NMAS client that allows it to use Universal Password, if configured. • iManager does not use LDAP for the initial iManager authentication process. It utilizes eDirectory’s proprietary authentication protocol. However, following initial authentication, iManager can, create LDAP connections to eDirectory as needed to support directory access for the installed plug‐ins that require LDAP access. • iManager does not support authenticating with eDirectory’s Simple Password. You might encounter the following error messages when authenticating to iManager. Each error message section discusses possible causes. • Section 8.1.1, “HTTP 404 Errors,” on page 88 • Section 8.1.2, “HTTP 500 Errors,” on page 89 • Section 8.1.3, “601 Error Messages,” on page 89 • Section 8.1.4, “622 Error Messages,” on page 89 • Section 8.1.5, “632 Error Messages,” on page 89 • Section 8.1.6, “634 Error Messages,” on page 90 • Section 8.1.7, “669 Error Messages,” on page 90 8.1.1 HTTP 404 Errors If you receive a 404 error the first time you attempt to access iManager, you need to verify the ports that Apache is running on. Depending on how you installed iManager and whether you chose to use Apache or IIS, the configuration file locations vary. Apache uses either the httpd.conf file or the ssl.conf file. Refer to the Microsoft documentation for information on IIS port settings. 88 Novell iManager 2.7.5 Administration Guide
8.1.2 HTTP 500 Errors If you receive an internal server error or servlet container error (either unavailable or being upgraded), iManager is having one of two problems with Tomcat: • Tomcat has not fully initialized after a reboot. • Tomcat has failed to start. Wait a few minutes and try again to access iManager. If you still receive the same errors, verify the status of Tomcat. Checking the Status of Tomcat 1 Restart Tomcat. For information about restarting Tomcat, see “Starting and Stopping Tomcat” on page 94. 2 Check the Tomcat logs for any errors. The log file is located in the $tomcat_home$/logs directory on the UNIX, Linux, and Windows platforms. On UNIX and Linux, the logs are named catalina.out or localhost_log.date.txt. On Windows, the log files are named stderr and stdout. 8.1.3 601 Error Messages The object name entered could not be found in the context specified. Some possible causes: • Contextless login might be disabled. • Your User object might not be in the configured search containers list. Either ask your administrator to add your user location to the contextless login search containers or log in with a full context. 8.1.4 622 Error Messages The NDS password has been disabled in the Universal Password policy. This may also manifest itself with a 222 Error Message. You can avoid this error with iManager Workstation by installing the client, which allows iManager to utilize the Universal Password authentication mechanism rather than eDirectory’s legacy authentication process. 8.1.5 632 Error Messages This error is a system failure with several possible causes (http://www.novell.com/documentation/ nwec/nwec_enu/nwec_ids_t_err_system_failure.html).
