[Zope] testing for local roles

Hi all, Is <dtml-if "AUTHENTICATED_USER.has_role('Manager','siteManager')"> .... </dtml-if> valid for local roles? siteManager is a local role. It seems that if I use this and there is a user with a local role present nothing is displayed. I'm wondering if there is a has_localrole(....) method of AUTH..._USER but I haven't been able to find it. -Aaron
