ZopeLDAP & LDAPAdapter, same problem?!?
by julio dinis 13 May '00

Hi Zopers. I just cant authenticate user with this two products, even tested with m$ldap and openldap. The problem is the same. The Products can see the users can validate pair login+password but after this something goes wrong, and the not authorized pops up. I created the atributes roles and domains. I give the user role Manager and the domain (tested different options: *, myip, none). I guess the problem is with this mapping of roles and domain to zope. Any further debug I can make? Any help? Thanx. Julio Dinis Silva ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Domain name change and start problem
by ed colmar 13 May '00

13 May '00

Hi! After registering my domain name, and reconfiguring my server, my Zserver will not start. I tried intalling a fresh zope, but I get the same error. I am new to linux, so I could be missing something obvious. Thanks for any suggestions. I have a x86 red-hat 6.1 system. The error I get: [root@linux zope]# Traceback (innermost last): File "/usr/local/zope/z2.py", line 493, in ? logger_object=lg) File "/usr/local/zope/ZServer/medusa/http_server.py", line 560, in __init__ ip = socket.gethostbyname (socket.gethostname()) socket.error: host not found

*REALLY* newbie question...
by Howard Jones 13 May '00

13 May '00

I've being playing on and off with Zope for a little while, and as a pet project to try stuff, I'm moving my own site to Zope. One of the things I wanted was a couple of sections on a page randomly pulled from a "pool" of possibles. I used this recipe from the "random content" howto: <dtml-var expr="_.whrandom.choice(Quotes.objectValues())"> and made a folder called Quotes with some DTML documents in it. However, when they are selected, the HTML is apparently escaped (I see the tags, not their effect). I can find an option for dtml-var to make it htmlescape stuff, but how do I make it NOT do that? why is it happening? Thanks in advance for any clues, Howard (the next section is picking/searching CD&Movie reviews from a MediaThings ZClass - erk!)

behavior of __setstate__ for version updates
by Scott Parish 13 May '00

13 May '00

I would like to use setstate to update my new product version; i can't however seem to figure out how to get it to work as i would like. Here is what i am trying. In my product, i have defined setstate as follows: def __setstate__(self, state): Persistent.__setstate__(self, state) if not hasattr(self, 'blah'): self.blah = "This is a test" I also have added: def change_blah(self): """ docstring """ self.blah = "That was a test" return "blah changed" I restart zope, and visit a page that uses a dtml-var tag to print blah. It prints "This is a test" as expected. I then visit the changed_blah page, and go back to the dtml-var page at which point it displays "That was a test", also as i would have expected. Now if i restart and go back to the page, it states "This is a test". Why wasn't the thing stored in the ZODB? Also, if i comment out my two lines in __setstate__, restart, and try to access blah, it doesn't exist? Why isn't it getting written to the ZODB at all? After grepping about, i found that Xen does a get_transaction().commit() after their setstate stuff, but doing that doesn't seem to do me any good either. Am i incorrect to think that this should opperate differently then this? thanks sRp -- Scott Parish http://srparish.net

Saving a rendered DTML document with LocalFS
by Jim Sanford 13 May '00

13 May '00

Any suggestions on an easy way to save a rendedred DTML document to a file with LocalFS? We have a DTML document that is a report that can be rendered on command showing the current status of orders. We send out a daily summary to an email list. The summary has a link to the archived detail report. Currently the detail report is brought up in the browser and we do a "Save as.." to save the renderd copy. I would like to automate the saving of the rendered copy. Any suggestions? Jim Sanford

LoginManager, Cookies, etc.
by Andrew Hughes Chatham 12 May '00

12 May '00

I've been working on LoginManager plugins this week, and I thought things were going very well. They are not going quite as well as I thought. I need to authenticate people using kerberos. Right now my plan is to just see if kinit fails using expect and maybe write python-kerberos bindings later. As a result, authenticating people is quite expensive, or at least it will be once it works :) But it's not our kerberos setup, so we need to protect the passwords or we'll get in trouble. So we need to initially authorize the person over a secure connection and then give them a cookie to authenticate them later over insecure connections. The BasicCookieLogin plugin just stores the password in the cookie, which is not good for us, so I wrote a RandomCookieLogin which puts a random number in the cookie and changes it every time they reauthenticate (load a page). It's not perfect security, but it's better than nothing. It all seems to work fine on my local machine, but then I realized that I'm going to need to be doing a move between port 80 and 81 with the cookies, which might complicate things. So I started testing cookies when I changed Zope's port, and it wasn't good. Shouldn't cookies work on all ports of the same machine? That was my understanding from skimming the RFC (why are those things so long?!) But they do not. If I authenticate while Zope is on port 80, restart Zope on port 81, the cookie is not reused. Of course it's conceivable that restarting the server killed the cookies (they don't work when I restart it on 80). If someone will just say "It's ok, Andrew, cookies will still work on the real setup; we've moved them from 80 to 81 and back all the time" I would be very happy. Is this something people have dealt with successfully? On a related note, I have experienced other forms of weirdness using cookies in Zope. I put "raise 'CookieError'" into _cookie_list in HTTPResponse.py to see when it was getting called. The traceback generated has a line something like this: File "lib/python/ZPublisher/HTTPResponse.py", line 213, in __str__ headersl=headersl+self._cookie_list() which seems just fine, as that is the way it gets called. But that text is on line 723. Line 213 has absolutely nothing to do with cookies. This certainly seems like more a Python bug than a Zope bug, but it's confusing (may not even be a bug, though I have trouble seeing how this would not be one). Also... (sorry!) if I try to add a domain field to a cookie, netscape does not take the cookie (I have warn before accepting cookies, so I can tell what's going on). Lynx seems to take it, but I'm not too worried about supporting thte lynx market. The header information that Zope's generating seems to be well-formed, but Netscape won't make the cookie. Has anyone used the domain field on cookies successfully? Andrew
