Bug Type: LDAP related
Operating System: Linux Redhat
PHP Version: 4.3.2
New Comment:
Did upgrade to said version, with a slightly larger degree of success
(32k, for example, consistently worked), but 35k and above continues to
never work. Here's a snippet of code which I use to test:

Description:
------------
ldap_modify, ldap_add, and ldap_mod_replace all hang when they attempt
to adjust an individual attribute with data roughly 31k characters or
greater. There is a threshold such that 30k and below works fine and
35k and above never works. Example:
$attrs = array();
$attrs['mnappparam'][0] = "tmpalkkllk...";
# strlen($attrs['mnappparam'][0]) is 32000
ldap_mod_replace($conn, $dn, $attrs);
# we hang, but if $attrs['mnappparam'][0] is 31000 or less, # we work.
It should be noted that cut-n-pasting (and modifying a little) and then
attempting to use ldap_modify (commandline), the entry works, no matter
how large. (Thus, definately a PHP bug.)
Reproduce code:
---------------
$attrs = array();
$attrs['mnappparam'][0] = "tmpalkkllk...";
# strlen($attrs['mnappparam'][0]) is 32000
ldap_mod_replace($conn, $dn, $attrs);
# we hang, but if $attrs['mnappparam'][0] is 31000 or less,
# we work.
Expected result:
----------------
It just hangs.
