The Daniels are on the right track, but not very clear:

First, the  elements all have the 'name' attribute set to 'email' and the 
'class' set to 'referral_1' etc. - I think you have that the wrong way round!


Second, using single quotes in the $_POST['referral_$i'] bit will not work (DPB 
is right there)  - use $_POST['referral_'.$i] or $_POST["referral_$i"]

[PHP] LDAP, Active Directory, and permissions

[Chris Knipe]

Hi,

I've found various sources and are successfully manipulating Active
Directory from PHP on our Domain Controller - frankly, things works much
better than I expected :)

I have now reached the point where I need to set permissions on objects in
Active Directory, i.e. to restrict read permissions to certain OUs and
objects within the directory (mainly related to Exchange stuff).

Is there anything in PHP which can be used to set permissions on AD
objects?  I haven't found any reference to doing this anywhere, so I thought
I'd give it a chance here... If not, then I suppose I'll have to code some
..NET application to act as a gateway between the PHP interface and Active
Directory, but naturally I would like to do as much as possible from within
PHP itself.

Many thanks,

I'm guessing that   is only valid in HTML.

Not sure why / would be encoded as it isn't anything too special
outside of the closing tag.

Re: [PHP] Fw: Spoofing user_agent

[Ron Piggott]

The following solution works:

I set my user-agent to:
VerseOfTheDaySitemapRobot/1.0 (http://www.TheVerseOfTheDay.info)

By doing:
ini_set('user_agent', "VerseOfTheDaySitemapRobot/1.0 
(http://www.TheVerseOfTheDay.info)");

When ran by a cron job this causes AWSTATS to treat the hits as:
Unknown robot (identified by 'robot')9704+18284.82 MB30 Nov 2010 -

The part which tricked me is that if I run the site map generator PHP script 
using a user interface the hits on the site are credited to the Firefox (the

Hrmm, yah. That must be an EE-specific thing... IIRC, in EE1, the

of the DB?

Ah, here we go:

[PHP] PHP shows nothing

[Mohammad Taghi Khalifeh]

Hi there,
I have a package written in pure PHP, some .php files that refer to others
via require_once(''),
but when I try to see package's contents via a browser, the pacakge just
shows nothing: a blank page.
I've activated all log levels, and it seems that php doesn't encounter any
problem.
I'm using PHP 5.3.3 and apache httpd 2.2.
FYI, I'm new to PHP and this mailing list :)
I would appreciate if someone could help me.

One of the irregularities about require_once is that if there is a
syntax error anywhere in the chain, the interpreter simply exits without
emitting anything. If you have display errors turned off, you get
nothing at all. There may be clues in the Apache error log, but don't
depend on it. To debug, enable errors temporarily, or print some bread
crumbs at the start of each file. That should at least help identify how
far you get before it fails.

Pacakges, as in the classes?   if you're trying to view a class file,
then yes, you won't (err... usually shouldn't) see anything.  If you
were to go to the main page that actually builds the pages, utilizes the
classes and stuff, then you should see something.

There is also another potential issue.  There was a godaddy server that
i used to use, i switched over a site to their servers, and all of a
sudden, the site didn't show up.   The issue was that there were either
trailing spaces after the ?>, or there was no closing ?> for the php
file.  

Make sure that the page you're trying to pull up has some kind of echo,
or at least output of any type... if that fails, then you can try
adding:
error_reporting(E_ALL);
to the top of the page you're trying to view, to see if there are any
errors it is generating.

just some things to think/check...

good luck, and Welcome to PHP!!!

the files are so many,  so I think tracking problem by printing some bread
crumbs at the start of each file is not easy,
something that might help is that I've turned on magic_quotes_gpc because of
the package developer's suggestion.
but I got this warning in both php log:
"PHP Warning:  Directive 'magic_quotes_gpc' is deprecated in PHP 5.3 and
greater in Unknown on line 0"
is this warning mean that 'magic_quotes_gpc' will not work properly? so
whats the alternative?

Mohammad;

Do the included files run OK?

If there are any errors in them, you may get a blank page.

To trouble shoot this, I typically place an:

 echo('aaa');

 in the first include. That way, if I see 'aaa' at the top of the web 
page, then I know the include has loaded properly.

No, As long as it is just a warning it still works correctly, The
message simply points out that magic quotes was a terrible idea and they
are finally going to remove it from the language. You should never have
to use it.

You will probably have to selectively add breadcrumbs to isolate which
file or files are causing your problem. Even if you put them in every
fourth file, you at least get some idea where to start digging.

As you recommended, by adding breadcrumbs, I found the hotspot: pg_connect()
Actually, somewhere php tryes to connect to postgresql via pg_connect().
The strange thing about it is that program dies in it without any echo.
providing connection information as $connection_string, the below block ends
the program:

if(!$db = @pg_connect($connection_string)) {
return FALSE;
}
return $db;

how can I find the problem and fix it?

The @ symbol is telling it to ignore errors.  Remove it and you'll see
them if that's where the problem is.

Chris,

1) Shouldn't the OU security permissions be set within the AD itself?
2) If the above is done, then the user account that's being authenticated
shouldn't be able to access privileged information.

Just curious, are you using phpldapadmin?

In Command line output, there was --with-pgsql=shared and
--with-pdo-pgsql=shared,
but phpinfo() did not load any library related to pgsql. so I figured out
that some libraries are not installed.
Installing php-pgsql package from fedora repos, problem solved.
Thank you so much for your help: it works for me very well. :)

Other thing that I want to know is that,
somewhereI read
that loading pdo drivers
as shared libraries are not recommended. whats wrong with that? and how can

1) Not sure.  The permissions I'm after is similar to that of NTFS
permissions on the file system.  Essentially, it is a way to restrict an
application to read certain OU's or Objects completely, making it invisible.
FYI... http://technet.microsoft.com/en-us/library/cc785913(WS.10).aspx

2) This is completely irrelevant to authentication.  See point 1 above.

I guess you didn't read far down enough to 'User Authentication':  'Active
Directory ... to access objects...'  (Note that every OU is the same any
network resource.)  That's exactly what I mentioned.  OU security settings
is similar to NTFS, user/group with the lesser privilege applies.

> 
> 2) This is completely irrelevant to authentication.  See point 1 above.

It's completely relevant, if you set the permissions on the OUs. (How do you
think have the access permission to the OUs?  Are a domain/enterprise admin?
Create a test a user account and an OU.  Set the security permissions.  Test
with the user account on accessing that OU and compare it to a domain admin
account.) The app that logins under a certain account would be restricted to
the set permissions.  If the users are using the PHP app then the app should
be passing the user's authentication along to AD for authentication instead
of a network service type account to login and then validate user's
authentication to see if the user is a valid.  Thus the security is
maintained/restricted to each individual login.  (Think of as network share
mapping.  You can login to a share and still change to a different user
account afterwards.)  If you try to do a work around in C# or a DLL of some
type as you mentioned earlier, you'll have to do the same thing.  So, I
strongly suggest you look into the adLDAP and modify accordingly if the app
isn't behaving as I mentioned.  Also, look into these [1] & [2].
