Bug #: 52303
Summary: NonLoginAuthenticator does not honour session timeout
with SingleSignOn Valve
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: br...@pingtoo.com
Classification: Unclassified
Created attachment 28052

proposed diff to fix org.apache.catalina.authenticator.NonLoginAuthenticator
This problem has been explored and discussed on the tomcat-users mailing list
under the title "SingleSignonValve and webapp session timeout". Basically, a
webapp that does not need to define a <login-config> is valid under the servlet
3.0 spec and therefore should be able to participate in a single signon realm.
It should be able to inherit the security principal established by another
webapp within the same realm. Its own <session-timeout> value should be
honoured, even when all the other sessions in the same SingleSignOnEntry have
expired.
The problem is with NonLoginAuthenticator - at some time it had SSO helper
logic that was too primitive. This logic was completely commented-out in tomcat
6.0.0.
I have two fairly simple webapps (not quite drop-ins) that demonstrate the
problem and my proposed fix. I have heavily commented my proposed fix to
explain the surrounding dependent logic that it relies on.
At the moment I have not found an SSO-based unit test for any of the
AuthenticatorBase concrete classes, but I will try to create one (eventually).
