GUF error: Unauthorized...
by Cesar A. K. Grossmann 28 Oct '00

Hi! I have created a GUFTest folder. It runs perfectly with the user 'jorge', provided with the GUF. After I have changed the acl to use a SQL connection, I'm getting the error bellow (in the log of the system): GUF[7909]: http://localhost.localdomain:8080/GUFTest/acl_users/userAuthenticate raised an exception (('Unauthorized', 'crypt', <traceback object at 85f10e8>)) The source of the HTML page contains (I don't know if it's correct, because I suspect that Netscape reloads the page when you ask it to show the source of the page):  What is wrong? I have created a local role called 'Usuario'. This role have the rights to: /GUFTest: Access contents information Can Login an Logout Use database methods View /GUFTest/acl_users: Access contents information Can Login an Logout Use database methods View The Anonymous role have the rights: /GUFTest: _no_roles_ /GUFTest/acl_users: Access contents information Can Login and Logout The userAuthenticate, userDomains, userList, adn userRoles DTML Methods are configurated to proxy the Manager role. I'm using Zope 2.2.1, on a Conectiva Linux 5.0 (Linux i386 2.2.14, python 1.5.2, glibc 2.1.3). TIA -- +---------------------------------+---------------------------------+ | César A. K.

Webdav Questions
by Darin Lee 27 Oct '00

27 Oct '00

Zopistas, I am working under Windows NT 4 and connecting to my Zope Server via the webfolders icon in "My Computer." I enter the IP address and port of my server, select finish, and a list of folders on the Zope server appears. However, I find that I am unable to edit, or even copy, any of the Zope objects. I keep getting an error message "An error occured while trying to copy some or all of the selected files". Here are my questions? 1. How is authentication being handled by my Zope server? Am I automatically authenticated to the server as the user I am logged on as on the local NT workstation? It never prompts me to identify myself via username and password. 2. Can the world at large view my Zope site via WebDAV? It seems that I can connect to the server from multiple machines, even logged on as users who are not in the Zope acl_users folder...Is this the default behavior? I have looked through the How-to's and performed searches on "Zope and WebDAV" in Google but haven't turned up much useful information. Can anyone offer any tips, or point me in the right direction on this? Thanks in advance, Darin Lee

How do I change dtml template on the fly in Python product?
by Max Møller Rasmussen 27 Oct '00

27 Oct '00

I have asked this question somewhat differently in another thread but here I go again from another angle, as it might have been my approach that was wrong to begin with. I have a Python product that allready does what I want it to, but I want to be able to create different views of the products content. (Model View Controller principle). To do this I have created a folder with different views (Or skins if you would prefer the Gnome/KDE way of saying it.) views view1 list.dtml view.dtml edit.dtml view2 list.dtml view.dtml edit.dtml In my class I have made a value that hold the name of the selected view, I call this: self.selView I want to make it possible to use the different sets of dtml files to create a different look and feel to the data. I want to write my "index_html" method so that it returns a rendered version of "list.dtml" corresponding to the selected view, by the name of the folder holding the selected view. something like this (which doesn't work): def index_html(): return HTMLFile('views/' + self.selView+ 'list') Is that the best way to do it?

Re: [Zope] Calling form elements by name

I should have posted your version, it's more explicit: ------------------------------------------- <dtml-in Items sort=Position> <dtml-let Prefix="'FormElement_'" thePos="_.str(Position)" nameAsAString="Prefix+thePos"> <dtml-var nameAsAString> <dtml-var "_['FromElement_1']"> <dtml-var "_[nameAsAString]"> </dtml-let> </dtml-in> ------------------------------------------- does not work either.

Securing ftp access?
by Paul Browning 27 Oct '00

27 Oct '00

Our local CERT-type person mailed me the following and I replied as follows. Could I have given a better answer? > I notice that zope comes with an FTP server which, by default, runs on port > 8021. There's one running on "stingray", as I write, which seems to accept > any and all combinations of usernames/passwords (valid or otherwise), > although *I* don't seem to be able to do/see anything with any of the ones > I've tried. Hmmm. Hadn't noticed that before. Even if you disable the FTP Access permission for the role Manager (as well as Anonymous) it's still the same. But, as you note, you can't do very much. > Anyway, that's an aside. What my question is is "how can this > service be used such that usernames/passwords are transmitted securely?" Don't know. Does SSL (whether Zope is behind Apache or not) only apply to http stuff? My understanding is that Zope incoporates the Medusa server. There is a reference on the Medusa web page (http://www.nightmare.com/medusa/) to "SSL and Medusa with STunnel". An exercise left for the ambitious reader? Meanwhile I observe that if you set a Domains restriction for a particular user (done via the acl_users Folder) it applies to both ftp and http clients (and presumably WebDAV too) - though at first it doesn't seem so via ftp because you can login, but you can't actually do anything (just like Richard reports with any username/password). So, an imperfect answer to your question might be "disallow ftp access from outside our local domain and then keep your fingers crossed". TIA.

RE: [Zope] More ZFormulator
by Spicklemire, Jerry 27 Oct '00

27 Oct '00

Steve asked: > What version of ZFormulator are you running (and in what version of > Zope?) I just tried ZFormulator-0.2 with Zope-2.2.2 and it seemed to > work OK. Maybe it doesn't work with older zopes? Oops, I should know better by now, than to ask for help without including the details. Zope 2.1.6 on Solaris 2.6 for Sparc, and Zope 2.2.1 on Linux 2.2 for Intel. The installs seemed to go smoothly on both systems, and I am able to create Form objects. However neither will let me add any form elements. The user authentication dialog pops up, and of coures I'm already authenticated at the initial access to the management interface. I'm both owner and manager of everything, but the authentication rejects my input. ZFormulator has been available since late 1999, so I would expect the older versions to be OK. Thanks, Jerry S.
