"Trace" is a technique for a user to request internal information about Tomcat. This is useful during product development but should not be enabled in production. Allowing an attacker to conduct a Trace operation against the Security Token Service will expose information that would be useful to perform a more targeted attack. vSphere UI provides the "allowTrace" parameter as a means to disable responding to Trace requests.
