's access to its database is configured incorrectly and when Maple T. A. encounters security problems when Tomcat Security is enabled with a multipleinstance 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/WEB-INF/lib. After that (and a Tomcat restart), Tomcat will usually log a great deal more information about the situation, helping problem diagnosis. 30 5 Implementing SSL Connections to Maple T. A. Configuring SSL is largely a Tomcat operation and has little to do with T. A. The Tomcat documentation contains instructions. See for example http://tomcat. apache. org/tomcat-5. 5-doc/ssl-howto. html. In the following, we summarize the steps. Refer to the Tomcat documentation for details. Note that it is possible to configure a Maple T. A. server to authenticate with LDAP over an SSL connection. This feature is different from enabling SSL with Maple 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. The following steps implement SSL for Maple T. A. : 1. Create a keystore with the certificate you want to use. 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 (non-SSL) 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.
