How do I implement SSO in Alfresco labs 3.0. Basically I am trying to get Alfresco work work with SiteMinder. I have the SiteMinder agents installed on the same machine as Alfresco. I would like to know what configuration changes are required to be done in Alfresco so that it integrates with SiteMinder. Also what do we need to add in the policy server for Alfresco?
