Hi, With basic authentication, the user's browser caches the username and password, and sends them along with each request. All you can do to invalidate the cached values is raise an "Unauthorized" exception. <dtml-raise type="Unauthorized"> You have been logged out. Please log in again. </dtml-raise> This sends an HTTP 500 Unauthorized back to your browser, which should display the basic auth. login box again. See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.12.html for details. hth, -- Marcus > -----Original Message----- > From: ibriones [mailto:ibriones@amutis.com] > Sent: 30 March 2000 10:36 > To: zope(a)zope.org > Subject: [Zope] Logout with standard basic authentification > > > I have tried to logout with standard basic authentification, > but I have > not seen nothing in Mailing List. > Only I have seen log out with cookie-based authentication, but i have > to use standard authentification.

SiteAccess officially breaks Zope 2.1.5, new version soon
by Evan Simpson 30 Mar '00

30 Mar '00

For those of you out there who use SiteAccess (or are considering using it) be aware that it dynamically patches ZPublisher to add a hook to the traversal process. This is a 'gorilla patch' which simply replaces a very large method, and is subject to breakage in the rare case where a new Zope release (such as 2.1.5) includes a change to this method. Zope 2.1.5 *will not work* with SiteAccess 1.0.0 or earlier. I expect to release version 1.0.1 this evening, which will be compatible with all 2.x versions of Zope, as well as fixing FTP access and providing a new feature to deal with SSL access. Cheers, Evan @ digicool & 4-am

Can I have 'pointers' to ZSQL Methods?
by Jason Wong 30 Mar '00

30 Mar '00

I need to do something like this: <dtml-in "<dtml-var qry_name>" or <dtml-in "_['<dtml-var qry_name>']"> where qry_name contains the name of the ZSQL Method that I want to use. However neither of the above works, the latter gives a traceback error, which I daren't reproduce here because of it's length :) The above is used inside a DTML Method which is called by passing parameters to it from a DTML Document. qry_name is one of the parameters being passed. Any help appreciated. thanks - Jason Wong Digital View Ltd 2201 Nanyang Plaza 57 Hung To Road Kwun Tong HONG KONG Tel: +852-2861-3615 Fax: +852-2520-2987 www.digitalview.com

RE: [Zope] Help ...........Desperate

[exec. summary -- concurrent requests becoming serialised; suggestions] Hi, I ran your test script on our zope server, and managed to view many other pages while zope was parsing the page... It looks like you might not have enough available threads (or maybe database connections?). It's strange that only one request at a time is processed -- are you perhaps using Zope in single-threaded mode (using pcgi_publisher; see doc/WEBSERVER.txt for details)? You can set the number of threads Zope uses by changing NUMBER_OF_THREADS in Zope.cgi; the default is 4. Note that increasing this number will also increase Zope's memory footprint, as each thread gets its own copy of the persistent object space. It may also be that your machine is simply choking on that test script -- it takes a while for zope to parse and render it. Despite python switching between threads every n bytecodes, such a script (rendering one million items) is going to put quite a load on the machine! On your database queries you may be using a database adaptor that doesn't give up the global python interpreter lock during transactions. This prevents other threads from executing. What database and database adaptor version are you using? See http://www.zope.org/Members/petrilli/DARoadmap for details. There is a brief description of why the interpreter lock exists in the python FAQ, section 4.88 (http://www.python.org/doc/FAQ.html#4.88) Although unlikely with only one user, it's also possible that you could be running out of database connections. By default, a maximum of seven connections can be opened to any database you add. This limit can be set by adjusting pool_size in zope_dir/lib/pyhthon/ZODB/DB.py (later versions of Zope allow you to tweak these things in a custom_zodb.py file; try searching the mailing list for details). Note that increasing pool_size will again increase Zope's memory footprint, as query results are cached on a per-connection basis. hth, -- Marcus > -----Original Message----- > From: Daniel G.

I have tried to logout with standard basic authentification, but I have not seen nothing in Mailing List. Only I have seen log out with cookie-based authentication, but i have to use standard authentification. I don't know how i can do it. What can I do to logout with standard basic authentification?

Some more strange permission/role stuff
by Andy Dustman 30 Mar '00

30 Mar '00

Environment: Red Hat Linux/Intel, Zope 2.1.6, GenericUserFolder 1.1.0 Problem: I have a GenericUserFolder in a folder in the root folder. When I log in to the initial Zope management screen, with a user with both Manager and Owner roles (andy), I get this as debugging output: 2000-03-29T21:23:04 PROBLEM(100) GUF gudid is Even though I am not going into the folder with the GUF. Probably this is due to just accessing contents information. Note that it says "gudid" and not "gufid", which is what's in the code, which is a bit odd. It's also printing some squirrely 8-bit character that doesn't paste in. The folder with the GUF (XXX) has acquisition turned off for all permissions, and all permissions enabled on Manager. The GUF itself has normal security. In addtion to this, the user is assigned the local roles of Manager and Owner in both XXX and XXX/acl_users. It doesn't seem to matter whether these local roles are assigned or not. If, as my user with Manager and Owner roles, I try to get into XXX, this happens in the debug log: 2000-03-29T21:23:26 PROBLEM(100) GUF URL is http://stan:8080/XXX in validate ------ 2000-03-29T21:23:26 PROBLEM(100) GUF Failed to authenticate with http://stan:8080/XXX/acl_users - crawling up ------ 2000-03-29T21:23:26 PROBLEM(100) GUF Authenticated andy with http://stan:8080/acl_users ------ 2000-03-29T21:23:26 PROBLEM(100) GUF Returning andy from http://stan:8080/XXX/acl_users validate (roles=('Anonymous',)) ------ 2000-03-29T21:23:26 PROBLEM(100) GUF URL is http://stan:8080/XXX in validate ------ 2000-03-29T21:23:26 PROBLEM(100) GUF Failed to authenticate with http://stan:8080/XXX/acl_users - crawling up ------ 2000-03-29T21:23:26 PROBLEM(100) GUF Failed Authentication with http://stan:8080/acl_users ------ The first three messages seem okay to me. The problem is that it is only validating my user for the Anonymous role, and from then it seems to be working as it should: It pops up a login document. The login stuff and authentication seems to work properly. But it is not getting the correct Roles from the top-level acl_users. The superuser works as you would expect, until you look at the debugging info. 2000-03-29T21:47:14 PROBLEM(100) GUF URL is http://stan:8080/XXX in validate ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Failed to authenticate with http://stan:8080/Starbase/acl_users - crawling up ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Authenticated superuser with http://stan:8080/acl_users ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Returning superuser from http://stan:8080/Starbase/acl_users validate (roles=('Anonymous',)) ------ 2000-03-29T21:47:14 PROBLEM(100) GUF URL is http://stan:8080/XXX in validate ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Failed to authenticate with http://stan:8080/XXX/acl_users - crawling up ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Authenticated superuser with http://stan:8080/acl_users ------ 2000-03-29T21:47:14 PROBLEM(100) GUF Returning superuser from http://stan:8080/XXX/acl_users validate (roles=['Manager', 'Admin', 'Engineer', 'Manager', 'User']) The difference here is on the first try (with andy), it crawls up twice and fails each time, but with the superuser, it again crawls up twice (gets just the Anonymous role at first), but on the second crawl, validates the correct roles (note that manager appears twice). Tracebacks dont look useful, just raising the LoginRequired exception, and the only reason I have a traceback is because of debug mode. Is this a bug (whose bug is it, anyway?) or a feature?
