Hi All, I was wondering if there is away to capture the users ID when I have someone login. I want to get the user name and find it in a database to determine if this person is a supervisor or not. Then let them see screens that others are not allowed access to. Thanks, Rex __________________________________ Do you Yahoo!? Yahoo!

Cookie Crumbler - How do I use it?
by Samir Mishra 04 Aug '03

04 Aug '03

OK I seem to be really dense on this, just can't figure out how to actually use the cookie crumbler product for form based authentication. Would someone have an easy sample I could learn from? Usually I'm OK at this stuff... Thanks for your patience. Regards, Samir

Site on a CD for Windows?
by Marc Burgauer 04 Aug '03

04 Aug '03

Hi We have developed a vertical market web solution for a reseller. We have also developed a demo web site for the reseller to show potential customers what the solution can do for them. After a few weeks of sales activities, it shows that a lot of their prospects do not yet have internet access. So when visiting them, the reseller can not demonstrate the solution. The sales people have asked us, if it would be possible to have the site on a CD. I can see two ways of doing this: 1.) Create a "static" version of the site that shows a set of pages illustrating what the solution could do. This would of course fail to demo the solution working. 2.) The more interesting thing would be to create a CD with a working version of Zope for Windows. As we're totally UNIX, I have absolutely no idea if this would be possible. I know Zope works Windows. What I don't know is how difficult is it to get it running. Can a normal Windows user (with no access to the Administrator's account) double-click a single .exe to get the sever running? (The sales people are not technical!) I envision a scenario like this: - Insert CD into PC - Run an "automatic installer" (Everything pre-configured, maybe with the exception as to where the files are installed to) - Open location of installation and double-click an .exe file - Open browser an point at 127.0.0.1:8080 (or something alike) My questions: Has somebody created something like this for Windows and could point me towards what I need to do? Is there free software to create the installer, ideally supporting an easy way to un-install as well? What requirements exist on Windows? (In other words, what can go wrong?) Cheers Marc

Problem with dtml-if sequence-start
by Borja Prieto 04 Aug '03

04 Aug '03

I have a problem with the following code, wich is a DTML methos that processes a form: <dtml-with REQUEST> (First, I check if the user has completed the txtCertificado field) <dtml-unless txtCertificado> <dtml-return "RESPONSE.redirect(URL1+'/InicioIC'+'?msg_error=Error: debe introducir un número de certificado')"> </dtml-unless> (Then, I lookup in a MySQL table with the method BuscaCertificado if a record with the value txtCertificado does already exists) <dtml-in BuscaCertificado> (if it is found, return with an error message) <dtml-if sequence-start> <dtml-return "RESPONSE.redirect(URL1+'/InicioIC'+'?msg_error=Error: el certificado '+txtCertificado+' ya existe')"> </dtml-if sequence-start> (and if not, go to IC page. This is the part that does not work) <dtml-return "RESPONSE.redirect(URL1+'/IC'+'?msg_error='+txtCertificado)"> </dtml-in> </dtml-with> The problem is that the program, though evaluates right the cases for nonexistent parameter or parameter already in the DB, it does not even reach the line: <dtml-return "RESPONSE.redirect(URL1+'/IC'+'?msg_error='+txtCertificado)"> Instead, it shows a blank page, with no code. There is no problem with this code, because I have tried changing it to show a simple message, and it doesn't work, too. Please, ¿could anyone tell me what I am doing wrong? Thanks in advance Borja Prieto Ursúa Alanta

RemoteUserFolder and local user attributes
by Brendan O'Connor 04 Aug '03

04 Aug '03

Hello all - I'm using the RemoteUserFolder product in an intranet portal that I've built for my company. So far the feedback has been overwhelmingly positive, with everyone starting to see the light. So far, authentication in my prototype site has been done within Zope. My IT dept supports an authentication mechanism that is done through apache allowing users to login using either their Unix or Windows passwords. It has been expressed to me as a requirement that I be able to use that information for logging users into the portal automatically. This problem would seem to be solved via the RemoteUserFolder since the authentication mechanism they use generates a REMOTE_USER field in the header. Unfortunately, the REMOTE_USER field is stuffed with a unique ID number (the employee ID number) rather than the more user friendly username. It's simple for me to get a mapping from employee ID number to username, but it is very expensive in terms of time. My initial implementation (which is a modification of RemoteUserFolder) just queries a database whenever a user needs to be authenticated to access an object. Naturally, this is very slow. Slow enough, in fact, to drive the load on the web server (normally 0.10-0.50) well over 2 whenever more than 1 person is accessing the portal. So, enough with my longwinded problem description ... I have considered the following solution (and would gladly entertain others, hint hint ..) When a new user is encountered, do the database lookup as part of the auto-add feature of RemoteUserFolder. Store the username as the user name and store the ID number as an attribute. That way, when a user needs to be authenticated, I can just match the ID number with the name within Zope and never have to go back to the database again. Seems reasonable ... only problem is that I can't figure out how to store the ID number as an attribute of the user. Any comments are welcome! Thanks in advance ... Regards, Brendan

Decisions, decisions! Which Python for Zope 2.6.2b5
by Dennis Allison 03 Aug '03

03 Aug '03

The installation notes still say Python 2.1.3. Rumor has it that you can run under Python 2.2 but it's not recommended. In fact, the docs say explicitly not to use it. I have been using Python 2.3 through the beta period and like it--the new language features have quickly become part of my programming lexicon. Zope 2.7 is not ready for prime time use on a production site. As I remember, it will require Python 2.3. I'm setting up a production site where stability and performance are important. Whould I use Python 2.1.3 or Python 2.3? I am planning to use Zope 2.6.2b5. We've been doing our development against 2.6.2b3 and have found it to be stable.

Newbie VHM/Siteroot question
by Vasu Muppalla 03 Aug '03

03 Aug '03

I am using zope standalone and have the SSL modules installed. Now I want to rewrite all management requests to the https ( runnin on port 8443). For this purpose, assume the URL has the string 'manage' in it. I tried using siteaccess, the following script as access rule. <dtml-let stack="_.string.find( URL, 'manage')"> <dtml-if expr="stack > 0"> <dtml-call "REQUEST.set('SiteRootPATH', 'https://localhost:8443/')"> <dtml-call "REQUEST['TraversalRequestNameStack'].append('manage')"> <dtml-else> <dtml-call "REQUEST.set('SiteRootPATH', URL)"> </dtml-if> </dtml-let> I get an error that resource is not found, blah blah. Resource is http: GET. With a string 'localhost' instead of 'manage' and SiterootPath = '/', the URL rewriting works. The error happens because of manage - dunno why. Is it possible to do it using only VHM and no siteroot ? TIA, Vasu

Zope threads on Slackware
by Heimo Laukkanen 03 Aug '03

03 Aug '03

Hi all, urgent need for help on Zope threads on Slackware linux. I'm not familiar with slackware and the sysadmin is not familiar with Python, but the situation is that somehow Zope does not run more than one thread on the system. Python is compiled with threads - and there seemed to be no errors on that. Zope is configured to start 4 threads. It looks like Zope tries to start the threads, but these threads die very fast ( in microseconds or so ). Any help on debugging would be appreciated. -huima
