pcgi + apache + manage authentication
by Paul Dwerryhouse 18 Jun '99

18 Jun '99

Hi all, I've got Zope going with PCGI using Apache, and I'm having trouble with authentication on the _management_ pages. Now, it all works fine with the superuser (I'm making use of the REMOTE_USER env variable, because I want Apache to handle all the password files) on all screens (including management screens), and it fine for normal users on document screens. But when a user goes to the management pages for a directory for which they have permission to manage, Zope pops up a box asking for user/password with an 'unknown' realm (as opposed to the "Zope-realm" that I've set up in Apache's config files). And it always fails, correct password or not. Why isn't Zope accepting the REMOTE_USER variable for the management screens? Using Zope 1.10.2 with Apache 1.3.6, under Linux (Debian)... Ta...

Login Button, sorted
by Phil Harris 18 Jun '99

18 Jun '99

Hi all Just a post to let you know how I solved the login button probloem I had yesterday. This is the DTML I used: <dtml-if "AUTHENTICATED_USER.has_role(['author'])"> <dtml-call "REQUEST.set('isallowed',1)"> <dtml-else> <dtml-raise Unauthorized> </dtml-raise> </dtml-if> <dtml-if REFERER> <dtml-call "RESPONSE.redirect(REFERER)"> <dtml-else> <dtml-call "RESPONSE.redirect('home_html')"> </dtml-if> It works for me, and may give other's some ideas.

Using ZServer with Apache
by Jim Cain 18 Jun '99

18 Jun '99

All, I have a Zope.cgi with INSTANCE_NAME that points to where I keep my database, but when I run ZServer with the following: python z2.py -p /home/httpd/cgi-bin/at/Zope.cgi -2 -w "" it's still referring to the var directory at the Zope installation instead of the one at INSTANCE_NAME. How do I get this to work?

Making zope work with ad serving software
by Andrew Bunner 18 Jun '99

18 Jun '99

First of all, thank you to everyone who's expressed interest in helping us with the EliteFitness.com project! We've been using a piece of ad serving software called Central Ad Pro. It can be invoked via two mechanisms...  -or- <img src="http://mydomain.com/cgi-bin/getimage.cgi/unique?ACCOUNT=my_account&BANN ER=my_banner"></a> Now, if you want to serve an HTML "banner", you have to you use the SSI mechanism... at least until we all have XML capable browsers and their fancy X-LINKS <g> My question is, what is an analogous way to embed the output of a CGI into a page served by Zope that will let us generate "useful" web logs? I read the thread about pulling the links off LinuxToday, so I understand that there are HTTP getting functions. I'm sure it's do-able, my main concern is that we're still able to analyze the click-through ratios of the banners! This makes me think we will have to use Zope with Apache. Is PCGI mutually exclusive with mod_perl? We already have mod_perl compiled into Apache since it servers another (non-Zope) site on the same machine. Does anyone have any thoughts on this? -- Andrew Andrew Bunner President, Mass Quantities, Inc. bunner(a)massquantities.com Professional Supplements for the Perfect Physique http://www.massquantities.com

Summary: revoking authentication
by Jonathan Corbet 17 Jun '99

17 Jun '99

Thanks to everybody who answered my question; I have gotten everything *almost* to the point I need. The problem, remember, was that I needed to be able to explicitly "log out" users of a Zope-powered site. The normal "basic" authentication mechanism does not allow for that - once the browser has its grip on your username and password, it doesn't let go until the browser restarts. (Which, with the 4.6 Netscape I just installed, is generally within about 15 minutes, but I digress...grumble...) The solution: get the unsupported UserDB product from http://www.zope.org/Download/Unsupported and install it. UserDB will authenticate users from an SQL database, which works well for my application. But, more to the point, it can be set up to use cookies for authentication purposes. Cookies can be reset from the server, thus allowing a "log out" capability. To allow users to log themselves out, simply give them a link to "acl_users/logout" and it happens. (NOT acl_users/docLogout, as suggested by one person - that looks like it works, but does not). The next thing to do is to add an expiration to the cookies, which I have not yet done. That deals with the "they forgot to log out" case - something that has been known to happen every year or so. Only one problem remains: I've not yet found a way to enable UserDB authentication in the top-level folder. Trying to set up UserDB there brings a complaint that acl_users already exists; Zope, however, will not let you delete acl_users from the top-level folder. That's an annoyance, but it can be worked around. I'm happy. Thanks again! jon Jonathan Corbet, Eklektix, Inc. corbet(a)eklektix.com

Our approach is to use FTP to get into the Object Database, and this is supported today, so long as you're using ZServer for your server. Having said this, while I think that SMB and NFS are interesting ideas, both have their own SERIOUS problems that are difficult to overcome. If you wish to undertake this, you should look at what hoops have to be jumped through to get FTP working... sorta. If you're using Windows machines, you should investigate IE5+WebDAV (which is called Web Folders)... this might be of some help. Please understand that while the object database might LOOK like a file system in some regards, it contains data which can not be expressed in any common file system, as well as organizational ideas which are completely foreign to the file-based world (such as acquisition).... just a bit of clarity. > Even so, I think I'm going to give Zope a whirl on a small project and see > what happens.
