LDAP 和 PHP 连接失败
我正在尝试通过PHP连接到安全的LDAP服务器(使用LDAP),但我遇到了问题。我收到以下错误
警告:ldap_bind() [function.ldap-bind]:无法绑定到服务器:无法联系第 16 行的 /var/www/test.php 中的 LDAP 服务器
当我尝试在没有 LDAP 的情况下进行连接时,我可以使用 LDAP,因为我将处理敏感信息。
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>";
}
?>
