Hi I have given up trying to manipulate acl_users from DTML for now - I'm sure it's possible because here and there on this list and on the Zope site I see hints that it can be done. However, I can't find (for example) a HOWTO anywhere that describes the API of acl_users and what you can do with it. Someone out there must do this sort of thing all the time, so don't be shy, write that HOWTO! (Or if I'm being really thick and there is one, just let me know where it is!) Failing that, maybe someone can suggest where to look in the Zope python source to find the methods acl_users exposes.
