我正在使用 PHP8 的 almalinux 8.7。使用 TLS 测试 ldapsearch 是可以的
ldapsearch -H ldap://xxxx -x -ZZ /etc/pki/tls/certs/xxxx.pem -D 'xxxxx' -w 'xxxx' -b 'cn=xxx,cn=users,dc=xxx,dc=xxxx'
但是 ldap_bind 不会找到 ldap 服务器。错误-1。没有ldap_start_tls($ldap_con); ， 没关系。
- 编辑错误信息：
我错过了什么？
if(empty(!$_POST["password"]))
{
// Configuration pour interface PHP de notre annuaire LDAP
$server = "ldap://xxx:389";
$login = $_POST['login'];
$password = $_POST['password'];
$basedn = 'dc=xxx,dc=xxx';
$group = 'xxxxx';
// Connexion à LDAP.
echo "Connexion...<br>";
$ldap_con=ldap_connect($server) or die('Could not connect to LDAP server.');
ldap_set_option(NULL, LDAP_OPT_X_TLS_CERTFILE, "/etc/pki/tls/certs/xxx.pem");
ldap_set_option(NULL, LDAP_OPT_X_TLS_KEYFILE, "/etc/pki/tls/private/xxx.key");
ldap_set_option($ldap_con, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap_con, LDAP_OPT_REFERRALS, 0);
ldap_set_option($ldap_con, LDAP_OPT_NETWORK_TIMEOUT, 10);
ldap_start_tls($ldap_con);
if (!@ldap_bind($ldap_con, $login . "@xxxx", $password))
{
// Ici on peut voir quelle est la vraie nature de l'erreur (commenter la redirection)
echo "<p>Error:" . ldap_error($ldap_con) . "</p>";
echo "<p>Error number:" . ldap_errno($ldap_con) . "</p>";
echo "<p>Error:" . ldap_err2str(ldap_errno($ldap_con)) . "</p>";
// Rediriger quand erreur

}
else

启动了 strace ps awux | grep sbin/httpd | awk '{print"-p " $2}' | xargs strace -f，但没有什么值得注意的。
php-fpm 上的 Strace strace -f $(pidof php-fpm | sed 's/\([0-9]*\)/\-p \1/g')
