Finally, with PHP 5.3 there is a paged search control available that
could be implemented in Net_LDAP2.
Currently i'm figuring out a good way to do this.

Hello!
PEAR Net_LDAP2 layers itself above phps ldap extension. This extension
does not export an paging mechanism, as far as i know.
The paged search control is a control that is usually set at the search
request, but php's ldap_search() function lacks an ability to provide
such controls, so im not sure wheter paged searches are suiported by
PHPs ldap-module.

Paged searches may be activated by providing general controls, please
see:
http://de.php.net/manual/de/function.ldap-set-option.php
The control for paged searches should be '1.2.840.113556.1.4.319'.

Unfortunately i did not had the time to experiment with controls - maybe
you like to assist?

Description:
------------
IS it possible to have a feature to page the searched results. This
exists in the Perl implementation of Net::LDAP, but I don't see it for
PHP.

Here are the links to the Perl Net::LDAP paging feature.

New Comment:

A possible way to implement this may be like the perl interface (needs
confirmation and deeper research):

- Extend the params-parameter to support a "control" key that can hold a
single control or an array of controls.
- Create a control superclass for general control handling (so to be
compatible to further search controls)
- Create a paging control class, extending control base class that
handles the paging cookie stuff
- extend search() to pass the paging-control object to
Net_LDAP_Search()
- extend Net_LDAP_Search to handle search results with cookies (it looks
like shiftEntry() and friends need to do successive searches with the
cookie)
That said, the actual LDAP searching code may have to be relocated from
Net_LDAP2->search() to a new factory method inside Net_LDAP_Search.


Usage in usercode would then be:
- Instantiate a paging control
- pass it in $ldap->search()
- be happy as Net_LDAP2 deals with the rest.

There is a branch in SVN now (implementingPagedSearches_PHP5.4) that
tries to implement this.

I hope that the target client code boils down to something like

____________________________
$pagesize = 200;
$pagedcontrol = new Net_LDAP2_PagedResultsControl($pagesize);

$searchparams = array(
'scope' => ....,
'control' => $pagedcontrol
);
$ldap->search(......., $searchparams);
... retrieve entries as usual from the search, it deals with the paging
internally
