Hi! For single sign on there is also CAS (Central Authentication Service). We're sucessfully using this in our Zope2 apps. It has plugin for PAS in Zope2 (CAS4PAS). CAS also works with other systems - plugins for java, php and other exists.
Important thing here is to distinguish between authentication and authorization. For example SSO like CAS can only tell you if your user is authenticated. It won't tell you if he has some permissions and/or roles to do something. But with PAS you can write another plugin that will set proper roles for user etc. -- Maciej Wisniowski _______________________________________________ Zope3-users mailing list Zope3email@example.com http://mail.zope.org/mailman/listinfo/zope3-users
