Bug: When creating new users on AD integrated WebReports implementations, Roles are not applied properly.  Whether you select one role or all, the user is created with no roles. If no roles are selected, you will get a notification that a role must be defined.  To overcome this, you must select at least one role during user creation and then manually edit the user to assign the appropriate role.
