's access to its database is configured incorrectly and when Maple T. A. encounters security problems when Tomcat Security is enabled with a multiple instance Tomcat web application structure, without compensating security policy configuration. In these cases you will see `Error listenerStart" messages in Tomcat's catalina. log, and very little else. To diagnose situations like this, it is helpful to remove the log4j jar file temporarily from <Tomcat>/webapps/mapleta/WEBINF/lib. After that (and a Tomcat restart), Tomcat will usually log a great deal more information about the situation, helping problem diagnosis. Configuring SSL is largely a Tomcat operation and has little to do with T. A. It is possible to implement both features, either feature by itself, or neither. For information on authenticating via LDAP over SSL, see section 6. 8. 6 below. You may place it anywhere, but the <Tomcat> installation directory is a convenient and reasonable place. In the <Tomcat>\conf\server. xml file, make the following changes: a. Disable the 8080 (nonSSL) connector definition by surrounding it with XML comment tags. <!-<Connector port="8080" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" /> --> 31 b. Enable the 8443 connector definition by removing the XML comment tags that surround it. <Connector port="8443" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="<keystore_path>" keystorePass="<keystore_password>" /> Provide <keystore_path> and <keystore_password> as appropriate. <keystore_path> may be an absolute path name or it may be relative to the <Tomcat> installation folder. In the <Tomcat>\webapps\mapleta\WEBINF\web. xml file, make the following two changes: a. In the ForwardRequest servlet section, set the port to that specified in the SSL connector (by default, 8443 ­ see Step 3 above): <servlet> . . . <init-param> <param-name>port</param-name> <param-value>8443</param-value> </init-param> . . . In the same section (ForwardRequest servlet), add the following: 32 <init-param> <param-name>protocol</param-name> <param-value>https</param-value> </init-param> 5. Usernames and passwords are stored in an LDAP server, typically administered by your institution's IT department, and used throughout the institution. supports the LDAP standard and should be able to use any LDAP server implementation. For example, we have customers using OpenLDAP, Active Directory, Sun ONE Directory Server and Novell eDirectory. [. . . ] A record for each assignment (excluding external assignments). 51 classes A record for each class. Includes name, instructor, inheritance information and a link to the course content in the records folder. An external assignment is one for which the question content is unknown ­ we only know question number and grades, as manually entered from external records. Proctors authorize students to start, re-enter and grade proctored assignments. [. . . ]
