Hi All,

I'm very new to LDAP and having a problem which hopefully someone will be
able to help with.  We're trying to retrieve values from an LDAP server
from within one of our applications.  I've got the sample application to
work and it retrieves values back.  If however the results are too large
(I'm guessing that this is the problem) I'm returned an error code of
LDAP_SIZELIMIT_EXCEEDED.  The C application is using the ldap_search_s

I can't find anyway of setting the number of items to bring back, is there
a way of doing this using the current function?  How do I determine what
the size limit is?  What do developers usually do when they need to bring
back thousands of entries when they hit this problem.  I must warn you that
I know hardly anything about LDAP so any simple and easy to follow advice
would be most welcome.

Thanks in advance,

Anyone have any ideas as to what might be wrong?

Your PHP module cannot find the OpenLDAP library when Apache starts.
You need to specify the path to the library (libldap.so*) for the PHP
module. I am not a big expert in PHP nor in OS X, but it is either done by
adding something
(extension_dir ?) in the php.ini file, or by adding the location to the
LD_LIBRARY_PATH. It could be also ldconfig, if OS X uses FreeBSD-style
