Ahh, I didn't even think of using multiple cookies :) If I understand you correctly, you're proposing something like this: Whenever Mailman is about to write a login page (i.e. the user is not already authenticated), it first issues a Set-Cookie: Mailman_cookie_test="This cookie is only used to test whether your browser will be able to authenticate with Mailman"; Version=1 HTTP header (If other Mailman cookies set attributes like Path or Domain, the test cookie should mirror these to make the test reflect real usage). Next, once the user has pressed the "Let me in..." button, Mailman checks whether the Cookie has been sent back. If it hasn't, authentication fails (as the user won't be able to make any changes anyway), and Mailman instructs the user to enable Cookies in her browser before retrying login. If the test Cookie is present, Mailman should issue a Set-Cookie: Mailman_cookie_test="clickety click"; Max-Age=0; Version=1 HTTP header (to delete the test cookie, so that the test cookie isn't later confused with test cookies for login attempts at other lists). Finally, Mailman proceeds with password authentication as usual, possibly resulting in an authentication cookie. Hmmmm... I guess the test cookie should contain info on what list it is for, as well. Have I understood you correctly? Does anyone think that implementing this (apart from my misunderstandings, of course :) would be a bad thing? And, while we're talking about cookies: Does anyone know whether switching from the cookie attribute "Expires" (which was part of the original Netscape cookie proposal) to the RFC2109 cookie attribute "Max-Age" is likely to cause any problems? I've had a look at Cookie.py, and the value part of the Expires attribute isn't enclosed in double quotes (in accordance with the original Netscape cookie proposal), which I believe might confuse Mailman in some situations where the browser sends back more than one cookie. Of course, if there are any (major) browsers in use out there that doesn't understand Max-Age, it would be a bad idea to change Mailman. -- Harald

I haven't seen this happen with my users, but as the offending piece of code indeed is a hack that won't work reliably if the browser sends multiple cookies, I think this should be addressed somehow. The real problem, I think, is that there's confusion on the subject of cookie content syntax. The original Netscape proposal uses this (not very well-defined, IMO) cookie content syntax: : NAME=VALUE : This string is a sequence of characters excluding semi-colon, : comma and white space. If there is a need to place such data in : the name or value, some encoding method such as URL style %XX : encoding is recommended, though no encoding is defined or : required. A quick example: [ Server -> Client ] Set-Cookie: CUSTOMER=WILE_E_COYOTE; path=/; expires=Wednesday, 09-Nov-99 23:12:40 GMT [ Client -> Server ] Cookie: CUSTOMER=WILE_E_COYOTE Note that there are no quotes around the cookie value. RFC 2109, however, has a more well-defined, but ever so slightly different content syntax: : 4.1 Syntax: General : : The two state management headers, Set-Cookie and Cookie, have common : syntactic properties involving attribute-value pairs. The following : grammar uses the notation, and tokens DIGIT (decimal digits) and : token (informally, a sequence of non-special, non-white space : characters) from the HTTP/1.1 specification [RFC 2068] to describe : their syntax. : : av-pairs = av-pair *(";" av-pair) : av-pair = attr ["=" value] ; optional value : attr = token : value = word : word = token | quoted-string Note that the cookies value can be a quoted-string. The example from the Netscape spec could look like this using the RFC syntax: [ Server -> Client ] Set-Cookie: CUSTOMER="WILE_E_COYOTE"; Version="1"; Path="/"; Max-Age="3600" [ Client -> Server ] Cookie: $Version="1"; CUSTOMER="WILE_E_COYOTE"; $Path="/" (Some time back) I looked over misc/Cookie.py trying to find some way to make it cope reliably with both kinds of cookies, but wasn't really able to discover what's wrong with _CookiePattern :( I suspect that using "Max-Age" attributes on Mailman cookies instead of the current (non-RFC) "Expires" attribute *might* help, but I really don't have any idea whether such a change will stop Mailman from working with certain browsers. -- Harald

Membership management chunking requires two authentications..
by Ted Cabeen 19 Jul '00

19 Jul '00

Mailman: 1.1 Python: 1.5.2 OS: Solaris 5.7 I don't know if this has been fixed in the CVS version, but I thought I'd submit it anyways. There seems to be a small authentication bug with the chunking in the membership management page. The page will load up correctly the first time it is accessed with the first chunk size shown. However, when you request a different chunk, it requires a reauthentication and then gives the chunk=0 page instead of the requested chunk. If you then click on the alternate chunk it loads fine. However, the additional click and authentication is annoying. -- Ted Cabeen http://www.pobox.com/~secabeen secabeen(a)pobox.com Check Website or finger for PGP Public Key secabeen(a)midway.uchicago.edu "I have taken all knowledge to be my province." -F.

What if there was a reserved word, say RANDU, that the subscription script would recognize. If you created a subscription box like I did, but in the hidden field put in RANDU, it would call the random algorithm that is used by mass subscribe to assign a password for the user. Those tiny boxes sure are convenient, it would be nice if a little hook like this could be put in to support it. --chris

I think that what this person wants is something like the quickie subscription boxes that you see for eGroups of ListBot. I have been working on something like this for a few lists that I run. As long as security is not that important, it is possible to work the subscription box into a web page. NOTE: this is a really quick kluge. NoTE: this is really not secure, I only use it on lists where it does not matter that much. To use: Drop into a page. Edit the ACTION line to point to the proper server/listname on your MM server. Also edit the two password fields so that they are the same. What this will do is provide an initial password for the user, making joining easy. What this will also do is provide the same initial password for all users, so IT IS NOT REALLY SECURE. At least change it to something sufficiently random looking to encourage people to change it themselves.
