[keycloak-user] Group's attributes not being mapped to users?

Hello, I use Keycloak 3.4.1.Final and keycloak-js NPM package as client. My use case employs a single level group hierarchy and users who belong to one of the groups. Each group has an attribute. For example attribute department_full_name. Thus users working in the same department could be grouped together and each would inherit its department_full_name attribute from the group. This way it feels natural to me. I've googled a relevant discussion: http://lists.jboss.org/pipermail/keycloak-user/2015-December/004042.html Also the Server Administration confirms this behavior by stating: "The Attributes and Role Mappings tab work exactly as the tabs with similar names under a user. Any attributes and role mappings you define will be inherited by the groups and users that are members of this group." However, it doesn't seem to work for me using Bearer OpenID Connect scheme. Decoded JWT structure simply doesn't contain my mapped attribute (in id_token or access_token). It contains both roles mapped from group and directly set user's attribute but not the group mapped attribute... Am I missing something obvious here? Thanks Andy
