Logout after ticket generation

[sorrentinov]

We have installed the pentaho-transparent-authentication and configured the mapping
We have generated ticket rightly and we are able to logon in pentaho using SSO.

The our problem is related to possibility to invalidate the session. We are not able to invalidate the session after ticket generation (even if we generate a new ticket). Is there a way to invalidate the session created from your plugin?

P.S. We are using Pentaho 6.1

Thanks in advance
Vincenzo
