We are switching from NIS to LDAP using Sun One Directory server 5.2.
I have to convert all our web PHP login scripts that are NIS based to LDAP.

I'm having difficult time just trying to do simple ldap_search, always coming up with "No such object in test.php on line 19. Below is the php code:

<?php

$info = array("userPassword","homeDirectory");
$rdn = "cn=proxy,ou=profile,dc=engr,dc=colostate,dc=edu";
$rdnPass = "password";
$basedn = "ou=People,cn=engr,cn=colostate,cn=edu";
$filter = "(uid=joeblow)";

$ds = ldap_connect("ldap.server.ip.here");
if (!$ds) {
print "System Error";
exit(0);
}
$bind = ldap_bind($ds, $rdn, $rdnPass);
if (!$bind) {
print "System bind error";
exit(0);
}
$sr = ldap_search($ds, $basedn, $filter, $info);
if (!$sr) {
print "Ldap_search failed\n";
}
else {
$info = ldap_get_entries($ds, $sr);
print $info["count"]." entries returned\n";
}
ldap_close($ds);
?>

Here are logs for the DS server:

I've tried compiling PHP against openLDAP and the native ldap libraries on Solaris 10 in /usr/lib. But get same error regardless. Any ideas what I'm doing wrong in the code?
And yes, uid joeblow does exist in LDAP.

client1 % ldaplist -l passwd joeblow
dn: uid=joeblow,ou=people,dc=engr,dc=colostate,dc=edu
objectClass: posixAccount
objectClass: shadowAccount
objectClass: account
objectClass: top
uid: joeblow
cn: joeblow
uidNumber: 902
gidNumber: 66
gecos: Average User test acct,,,
homeDirectory: /top/students/UNGRAD/ES/joeblow/home
loginShell: /bin/csh


Thanks...
