ALF SSO is the framework used in SBM and is based on the Eclipse Higgins project. There many references in the Eclipse site related to ALF SSO, however there is complete documentation of Higgins. Be sure to use the documentation associated with the version of Higgins found in SBM.
The build is 1.1 M3. TokenService.war is where the Higgins code, configuration and WSDL contracts reside. The ALFSSOLogin.war is where our implemetation is configured. Please keep in mind this is not supported, so make backups of everything you modify. Additionally, the support team will not be able to assist either, as any integration that is "home grown" would be next to impossible to troubleshoot.
