LDAP 和 PHP 连接失败

I works when I try to connect without LDAPs, but it is required that I use LDAPs because I am going to be dealing with sensitive information.

我正在使用以下代码

<?php
// basic sequence with LDAP is connect, bind, search, interpret search
// result, close connection

echo "<h3>LDAP query test</h3>";
echo "Connecting ...";
$ds=ldap_connect("ldaps://server");  // must be a valid LDAP server!




print $ds;

if ($ds) { 
    echo "<br><br>Binding ..."; 
    $r=ldap_bind($ds);     // this is an "anonymous" bind, typically
                           // read-only access
    echo "Bind result is " . $r . "<br />";

    echo "Searching for (sn=S*) ...";
    // Search surname entry
    $sr=ldap_search($ds, "ou=people,o=server.ca,o=server", "uid=username*");  
    echo "Search result is " . $sr . "<br />";

    echo "Number of entires returned is " . ldap_count_entries($ds, $sr) . "<br />";

    echo "Getting entries ...<p>";
    $info = ldap_get_entries($ds, $sr);
    echo "Data for " . $info["count"] . " items returned:<p>";

print_r($info);
//    for ($i=0; $i<$info["count"]; $i++) {
//        echo "dn is: " . $info[$i]["dn"] . "<br />";
//        echo "first cn entry is: " . $info[$i]["cn"][0] . "<br />";
//        echo "first email entry is: " . $info[$i]["mail"][0] . "<br /><hr />";
//    }

    echo "Closing connection";
    ldap_close($ds);

} else {
    echo "<h4>Unable to connect to LDAP server</h4>";
}
?>

推荐答案

此问题与实际绑定过程(无效凭据)无关，因为如果 LDAP 服务器无法验证您的凭据，警告将是不同的.但正如 Paul Dixon 指出使用 ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION,3) 应该是必需的 - 即使我认为这不是你的问题的原因.
