Warning: ldap_bind(): Unable to bind to server: Can't contact LDAP server in d:\greenamp\www\cmailnet\test.php on line 7

At the server end, run slapd in max. debugging mode:

# /path/to/slapd -d -1 -u ldap

ulmer

What's wrong? =>; PHP script? or LDAP slapd?
firstly test your ldap! running or death ?

$ telnet your.ldap.host ldap

or

$ ldapsearch -x -h your.ldap.host

if ldap running, is the error from PHP! otherwise
check more slapd.

i am using winxp not linux, then...

eingmarra

i tested
my ldap's path is
greenamp/openldap/
i in this fold key in .\slapd -d 256 then i saw "slapd starting"
is it means the ldap server has been powered on???

eingmarra

i key in "telnet localhost 389" when i powered on openldap
it works!
but the problem"Warning: ldap_bind(): Unable to bind to server: Can't contact LDAP server in d:\greenamp\www\cmailnet\test.php on line 7" existed also

好象是php 不支持ldapv3协议的说！！

eingmarra

i have resolve this problem
look my program


<?
$ds=ldap_connect("localhost","389"
        or die("Could not connect ldap";
               
if (ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {
    echo "Using LDAPv3<br>;";
} else {
    echo "Failed to set protocol version to 3<br>;";
}

    $r=ldap_bind($ds);   
    echo "Bind result is ".$r."<br />;";
?>;

in php manuel i found if the version of openldap >;2 the php will have some problem on ldap_bind(); because php try to use ldapv2 to bind, but the >;2 version openldap use ldapv3.
so you must key in:
  if (ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {
    echo "Using LDAPv3<br>;";
} else {
    echo "Failed to set protocol version to 3<br>;";
}

It is ALWAYS a good idea to add this directive to slapd.conf so that OpenLDAP could answer BOTH v2 or v3 connection requests.

allow bind_v2 bind_anon_dn
