Earlier than current versions of GUF automatically did this, but I changed it in the later releases after I saw the error pointed our by Ty or Phillip - this may be a source of some confusion.

A logged in user may not get the "Anonymous" role. This does not provide additional security, because this user may simply shut down his browser and access the page again as anonymous user. On the other hand, it may result in surprises: suddenly (after a log on) I can no longer do things that I was able to do before the log on. I think, this should be changed.

This is natural, too. Why should a registered user have less authorization than an anonymous one. Or, to put it another way, just because an acl_users folder doesn't know anything about a user, why should that user not have the anonymous role? Thus, two reasons to change the Zope authorization, such that each user has implicitely the "Anonymous" role, if this is not the case now.

Dieter Maurer wrote: In Zope, each user has a set of roles. Any user has the "Anonymous" role. Log-in users may have additional roles. I'm not convinced this is true... Quoting from the LoginManager CHANGES.TXT file: Generic User Source, like the GenericUserFolder product it was inspired by, gave all users the Anonymous role. This seems to be incorrect according to what other user folders do, including the standard Zope version, so GUS now no longer does this. ...which is why Alan experiences this problem. I've also run into it just using a normal acl_users folder and I've been mentioning every few months since I bumped into it back in March. Here's my opriginal post: http://zope.nipltd.com/public/lists/dev-archive.nsf/ByKey/82AE22A20C7E88AE I wish this could get sorted out as it makes security a nightmare unless you use a web of local roles, which is painful and messy to maintain. Is there any reason why every user shouldn't have the anonymous role for every accessible page/object/thing visitable through a protocol? cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] Authentication, Anonymous and Public
I thought the same. Perhaps the use of NT User causes this? Since the browser has the credentials to authenticate to NT and the higher folders are not aware of the NT User Folder... Seems the only solutions are to use the NT User Folder at the root level.
