Zope scripting and ownership
by Isaac To 01 Dec '02

01 Dec '02

Hi, Is there any way for a Python script to control who is going to be the owner of a file it generate? My testing show that a new object created using manage_X method is always owned by the authenticated person, even if it is created by a proxy script and the authenticated person normally have no right to create a new object in that folder. Is it possible to write a script that change the owner at the time when an object is created, or after the object is created, say if the script is a manager proxy? Regards, Isaac.

Do I have to install Python in a different directory as a seperate software? The product ParsedXML nedds this library. Thank You for help Fritz

[ANNOUNCE] JTracker simplified issue tracker released
by Jens Vagelpohl 30 Nov '02

30 Nov '02

The JTracker product provides a simple issue tracker that was inspired by the original ZClass-based Tracker product and its replacement, the Collector. I decided to "roll my own" because I disagreed with the complexity of both these packages, the policies and usage patterns encoded in them as well as the disruptive design of the user interface which disrespects existing site design. I found it very tedious to use as the administrator and sole supporter. The last straw was the fact that the Tracker prevented me from upgrading my own sites to Zope 2.6.x because it is incompatible with some change between 2.5.1 and 2.6. I am using the JTracker for issue tracking on my own supported software packages (including LDAPUserFolder, MaildropHost, JRedirector and more) and its simplicity and openness to the administrator users makes my life easier. JTracker has been driven (and will continue to be driven) by my own needs and policies and might not be suitable for every application. You can find the JTracker at http://www.dataflake.org/software/jtracker/ . Feedback is highly encouraged and can be entered into the JTracker instance at dataflake.org at http://www.dataflake.org/software/tracker . jens

[ANNOUNCE] First LDAPUserFolder 2.0 beta released
by Jens Vagelpohl 30 Nov '02

30 Nov '02

The LDAPUserFolder product provides a Zope user folder implementation that can authenticate users with the help of a LDAP directory. It has a full range of record management tools and uses caching of LDAP data to improve responsiveness. Version 2.0 represents a major code base refactoring. The main goals were code simplification, cruft removal and improving maintainability for me. While this meant putting the axe to some features it also enabled me to implement some other functionality that would have been much harder to do using the old code. Every current LDAPUserFolder user is encouraged to try the new version and provide feedback. Some of the main changes include... o Deprecation of built-in cookie support. If you need cookies you can install the excellent CookieCrumbler product. See http://www.zope.org/Members/hathawsh/CookieCrumbler for more information. o Deprecation of ZBabel support. Few people provided any feedback on it and it was a PITA to maintain the translations. o You can now specify multiple LDAP servers that are used for failover in case the primary server is down. o The usage of a Manager login can be specified in a more fine-grained fashion so that it is possible to restrict its usage to initial user login only when the user record needs to be looked up. o A new object called LDAPUserSatellite allows manipulation of roles depending on the context the user is in. Roles can be added by either providing simple mappings (Role X is mapped to roles A, B and C in this context) or by providing another LDAP group record search base to complement the search base used by the LDAPUserFolder itself. This role manipulation can also be done recursively, meaning more than a single LDAPUserSatellite can be applied in a single lookup. You can find version 2.0 beta1 of the LDAPUserFolder at the usual location at http://www.dataflake.org/software/ldapuserfolder and feedback is welcome in the JTracker set up for it under http://www.dataflake.org/software/tracker/ . jens

[LDAP] Does LDAPUserFolder work with Zope 2.6.0?
by Colin Sampaleanu 30 Nov '02

30 Nov '02

Can anybody confirm that LDAPUserFolder (1.6 beta 2) works ok with Zope 2.6.0? The docs mention it working with 2.5, but make no mention of 2.6. I am having some major issues) described below, which seem to stop me from being able to run it at all. I am running RedHat 7.3, openldap-clients-2.0.23-4, python-ldap-2.0.0pre06, and am trying to use LDAPUserFolder 1.6 beta 2. I have installed pythin-ldap for the copy of python included in my zope install, and have verified that I am able to connect to the LDAP server (MS Active Directory in this case), so there are no issues at that level as far as I can tell. When I try to add an instance of the LDAPUserFolder, pressing the 'add' button results in a 'hang', with my browser never coming back. If I am browsing the zope mangement tree, and then try to hit the folder with the ldapuserfolder also 'hangs'. If I shut down everything, and hit the management url again (coming in completely unauthenticated), then I get the browser id/password popup, and entering in a name and hitting enter will also result in a hang. I am able to go in via the zope admin/emergency use, and take a look at the ldapuserfolder, which seems to be ok, and kill it, etc. So as far as I can tell, LDAPUserfolder is simply hanging when it goes in and tries to do a lookup. There is no exception, and nothing put in the log. Any suggestions would be much appreciated... Colin

How can be sure to be safe when a new version of a Product is released ?

Hi, I know Plone beta3 is a beta version... it's only a case example ... as several css in plone_styles went missing, all the customized stuff using them explicitly go wrong [the migration was for me a (relative..) catastrophy, as in the process of learning, I just tackle customizing (not filling my site with contenus) ] danielle d'avout

LDAP Database and Zope user folders
by Josef Meile 30 Nov '02

30 Nov '02

Hi, I was looking at the code of the LDAPUserFolder and realized that it inherits from Object Manager. I'm just wondering if this is necesary. Does an user folder have to store some temporal data of a user while he's connected? or is it enough with the cookies used by zope? The reason of my question is that I want to implement a very simple user folder that directly authenticates a user against a LDAP server without searching his DN on the database. In my case, I know that all the DNs of the users of my system are the same except by the username and password, so I could do something like: import ldap LDAPSERVER=ldap.initialize(LDAPServerUrl+':'+serverPort) LDAPSERVER.bind_s('cn='+userId+baseDN,userPassword,ldap.AUTH_SIMPLE) I tested that code and it worked fine. My problem with the LDAPUserFolder is that if the server doesn't support anonymous connections, I'll need a bind password and username because this product searches the user's DN and then sends it with the user's password. The people from technical doesn't agree much with this approach. For they would be better if I did directly without such information. Thanks in advanced, Josef
