Not sure if it's this release version I'm using I normally get the stuff from
cvs but I have the snapshot from around october last year with probably a couple
of files updated from cvs, relating to stopping back button re-authentication.

It is being used on a couple of site and on our intranet with no problems.
We're using the session4_custom class with register globals off on php 4.1.2

I would check the release notes of that release against the cvs and update any
files that need it. I haven't had a look in the cvs for a couple of months so
I'm not sure if anything new has been added which may affect stability

See above, but works fine for me.

Re: [Phplib-users] couple of questions

[Dennis G. <ge...@cv...>]

When a page is doing a login because the user filled in information on a
public/nobody page and is going to a private/login-required page, all
the cookie/get/post has to be saved into the session vars until login is
complete or not.

So getting rid of register_globals would require that circumstance, i.e.
loggin in, to :
	Save the http_referer
	Save the post/get/cookie vars
	Maybe save the whole CGI environment,
Do a login/registration
	Send the user back to the starting page, with variables intact
	send the user to the target page, with variables intact.

Is this a normal scenario, to save GPC vars, or just the global vars? If
just global vars, there has to be a way to store and retrieve GPC/CGI
vars, and restore them to the correct 'HTTP_*_VARS' or '_*' arrays. I'm
not even sure if those are writeable, which might make the point moot!

[Phplib-users] another question

[Dennis G. <ge...@cv...>]

Is there a version of db_pgsql for postgres that no longer uses the split container?

[Phplib-users] couple of questions

[Dennis G. <ge...@cv...>]

1/ is 7.4 pre 2 being used by anybody in production yet? Comments?

2/ is the need for register globals going to be entirely wiped out when this is released, (I'll be 
turning it off in my installation)?

Re: [Phplib-users] unable to connect

[BRUN L. <zi...@cl...>]

I use the RELEASE 7.4-pre2 version, and i tought it was because of
register_globals wich is set to on (in reffer to this post :
http://sourceforge.net/mailarchive/message.php?msg_id=2832431 ).

i put it to off and restart Apache, but i still can't log with the page
test.

Any idea of the way to debug the prob ?

Re: [Phplib-users] unable to connect

[Peter C. <li...@kr...>]

Hi Lilian

Which version of phplib are you using? - the more recent versions use php4's native sessions, so no data will be written to the phplib session tables.

So you might not have a problem at all!

I think if you do want to use the tables, you need to user session4_custom.inc - but I've not used it, so maybe someone else culd help you there if you need it.

Hope that helps

Peter

[Phplib-users] unable to connect

[<zi...@cl...>]

I read carrefuly the install doc and test it, but i'm finally unable to co=
nnect to the test-example page with the default kris/test logon.
I had created tables and the test to the database is successfull : =

<?php
  include(=22table.inc=22); // requires include=5Fpath to be functioning

  =24db =3D new DB=5FExample;
  =24db->query(=22select * from auth=5Fuser=22);

  =24t =3D new Table;
  =24t->heading =3D =22on=22;
  =24t->show=5Fresult(=24db);
?>

look like this on the page :
user=5Fid username password perms =

c14cbf141ab1b7cd009356f555b607dc kris test admin =


the session test work too, but not at all : =

the counter works, but i dont get any lines in the session table.

So, i think i miss a stage but i spend hours to find it without success ..=
=2E

Could u help me ?

In a perfect setup world, all links should be relative then? What about 
images.
Shouldn't be desirable to bind the (https) protocol to the authenticated
session and logout in case lost?

I am telling this because I obviuosly advanced from the get/cookie stall ;-)

The latest release reflects the state of the -stable cvs.  This contains 
the latest php4 sessions code.

http://sourceforge.net/project/showfiles.php?group_id=31885&release_id=133677

There is a development snapshot that contains some patches submitted, 
including an alternate auth class by Giancarlo.  Look for 
phplib-0.74.datestring.dev.tar.gz here:

http://phplib.sourceforge.net/snapshots/

Note the .dev.tar.gz.

[Phplib-users] an interesting paper

[Giancarlo <gia...@na...>]

I am reading 'Dos and Don'ts of client authenticaytion on the web', by 
Kevin Fu and others
http://pdos.lcs.mit.edu/cookies/

it proposes an cookie recipe that is composed of 3 parts.
1. Our SID, called 's'
2. another ever-changing value (eg expiration, or even an incremetal, or 
a random md5 hash), called 't'
3. a third value that is a digest of the first two PLUS a secret part, 
's'+'t'+secret word

This way noone can invent a session ID or twiddle the expiration part, 
cause the third part would not match as he does not know the secret part

Although phplib keeps the expiration on the db, that recipe would be OK 
for cookies and URL as long as the second value is ever-chainging.

[Phplib-users] more on session fixation...

[Giancarlo <gia...@na...>]

Reaing that paper mentioned now in the php manual, titled "Session 
Fixation",  one is taken to think that https can help in quite a bit of 
cases. As I started reflecting on this, it is clear that, whenever you 
carry some token-credential in your headers, eg a session cookie that 
grants authentication, it is safe to travel inside the SSL tunnel. And 
stick to it. Because anytime you inadvertely click on a link that has 
not 'https' in front of it, you transit all you headers openly through 
the net, with no encryption. I know there are 'secure' cookies, that 
would only exist inside https.
My question is: who's task is it to prevent the user exiting the SSL 
tunnel while still carrying all his credentials? Is it reasonable that 
an athenticated user can go in and out the https protocol, without 
loosing any of his authentication? I know this is all obsolete, because 
we all are goig ti use client certificates, but for the meantime this is 
what we have to cope with, as Maxim wrote.

[Phplib-users] news in php 4.3.2

[Giancarlo <gia...@na...>]

reading NEWS in 4.3.2 I found
- Added session_regenerate_id() function. (Sascha)

I think this should give the possibility to transit any session into a 
new session, eg once authed.

And then I see that my old fixation about providing unadverted user with 
a preexisting session, has been widely accepted as evil. PHP doc 
mentions a nice doc, titled "Session Fixation"

[Phplib-users] Challenge_Crypt_Auth doesn\'t seem to work - All fixed

[<pau...@mo...>]

Dear All

I figured out what was wrong with the above.  The code in local.inc for auth_validatelogin() uses the num_rows() method which always returns 0 on an oracle select statement.  Altering this fixed the problem.

[Phplib-users] Challenge_Crypt_Auth doesn\'t seem to work

[<pau...@mo...>]

Dear All

I am having some difficulty with Challenge_Crypt_Auth (phplib-7.2d).  If I set auth to the standard auth class, I can log in no problem usng kris and test.  However if I user either Challenge_Crypt_Auth or Challenge_Auth I just get returned to the login prompt with the message \"Either your username or your password are invalid.  Please try again!\"

I am having great difficulty tracking down where the problem lies with the code spread thru page.inc, local.inc, crcloginform.ihtml etc.

Can some one confirm that all the checking is done in auth_validatelogin()?

Many thanks

Paul

Hmmm.  This smells like a bug.  You might try setting max_user_connections
to something extremely large, like 1000, and see if this helps.
 
> can I change someting in my PHP Scripts? (close DB)

using connect() rather than pconnect() might help, but isn't this hard-coded
into the phplib database object scripts?  Lowering the wait_timeout for
pconnect() might also help, but if mysql isn't honoring the
max_user_connections setting then who knows.  If your server isn't setting
up persistent connections on a pconnect call then this might not help.

This is a mysql issue.  You can change max_user_connections in your my.cnf
file.  Do a locate for it on your system.  This is often set to 0 (no limit)
but may be set to a specific value which is too low for your situation.  You
can see the current setting by logging in to mysql with the mysql client and
giving the 'show variables;' command.

To set max_user_connections, edit my.cnf and under the [mysqld] section, put
the following line.

set-variable    = max_user_connections=0  
                                        
Restart the mysql server and the problem should go away.

This assumes that you administer your own server.  If not, you'll need to   
get the server admins to take care of the issue.
