Ok, thank you for your answer. Anyway I'm not able to understand what Group Type means. Using the scripts found in the Wiki I have created the base configuration on my MySQL JBpm Data Base. I logged in as "manager" and in the Identities link I have added a new Group called "baseusers". In this moment there is the possibility to specify the Group Type. But which values are availables? (it's the same question of my previous post), so I have left this field blank. Then I have created a new user called Stefano and I have added a Membership to this user with the "baseusers" group. With this new user I'm not able to login. Why? I get HTTP Status 403 - Access to the requested resource has been denied If I don't use my Group (baseusers) I'm able to login using Stefano just if I add membership with all the existing pre-defined groups - admin - sales - manager - hr - sales Sorry kukeltje, I know that I'm a complete newbie but for me it's very difficult to understand how Jbpm works about this configuration.
