TCAT-AS-001080 - Application user name must be logged.
Information
The access logfile format is defined within a Valve that implements the org.apache.catalina.valves.AccessLogValve interface within the /opt/tomcat/server.xml configuration file: The %u pattern code is included in the pattern element and logs the username used to authenticate to an application. Including the username pattern in the log configuration provides useful information about the application user who is logging in, which is critical for troubleshooting and forensic investigations.Solution
As a privileged user on the Tomcat server:Edit the $CATALINA_BASE/conf/server.xml file.
Modify the <Valve> element that is nested beneath the <Host> element. Change the AccessLogValve setting to include %u in the pattern= statement.
EXAMPLE:
<Host name='localhost' appBase='webapps'
unpackWARs='true' autoDeploy='false'>
...
<Valve className='org.apache.catalina.valves.AccessLogValve' directory='logs'
prefix='localhost_access_log' suffix='.txt'
pattern='%h %l %t %u "%r" %s %b' />
...
</Host>
Restart the Tomcat server:
sudo systemctl restart tomcat
sudo systemctl daemon-reload
