Description Brian Stansberry 2004-03-30 06:39:57 UTC
The attached patch is a first step aimed at enabling TC's SingleSignOn 
function to work across a cluster.

It includes the following:

1) Interface SSOClusterManager, which should be implemented by a class that 
provides SSO support across a cluster.
2) Changes to SingleSignOn (and related classes) to add an MBean attribute for 
specifying an implementation of SSOClusterManager to use.  If an 
SSOClusterManager is set, invokes it when changes are made to the SSO entries 
on the local cluster node or if the cluster needs to be queried for a non-
local SSO.
3) An abstract base implementation of SSOClusterManager that concrete 
subclasses can build upon.

FYI, I have also attached a concrete implementation, a 
JBossSSOClusterManager.  It uses the JBoss TreeCache to 
communicate SSO changes across the cluster.  I've tested this in the 
JBoss/Tomcat integration. I know you can't use TreeCache in TC because of 
license issues, but thought you might be interested in a concrete 
implementation.

Sorry, I haven't had a chance to look into how Tomcat's own cluster 
communication works.  If you're interested in this patch I can look into what 
it would take to implement a TC-only version.

SSOClusterManager implementation for JBoss
Comment 3 Remy Maucherat 2004-04-26 22:00:33 UTC
I had started reworking the code, but you were faster. So now I think only an
extended valve is needed, but it will obviously go in the JBoss repository.

I can add it to my todo list, this should be very simple to implement into 
Tomcat clustering as well. I'm not biased like Remy ;-) to put it into JBoss, 
he he he

Ping to Filip: still feel like to doing this one?
Comment 6 Filip Hanik 2004-12-08 21:36:16 UTC
I just added it to the todo list, but no I have no timeframe mind of when this 
could be reality
Comment 7 Mark Thomas 2011-12-20 20:31:46 UTC
This Tomcat 5 enhancement request has been moved to Tomcat 7 (the latest version) since Tomcat 5 development is limited and focussed on bugs and security issues whereas Tomcat 7 is still seeing new feature development.
Comment 8 Mark Thomas 2015-02-01 19:33:00 UTC
This has largely been implemented (see the duplicate). Just awiting feedback beforeback-porting it to 7.0.x.
