Estoy en almalinux 8.7 con PHP8. Pruebe ldapsearch con TLS está bien
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'
Pero ldap_bind no encuentra el servidor ldap. Error -1. Sinldap_start_tls($ldap_con);, está bien.
- EDITARmensaje de error :
¿Qué me estoy perdiendo?

Probablemente exista cierta confusión entre StartTLS y TLS, son dos cosas diferentes.
Cuando usa StartTLS, se conecta al puerto de texto sin formato (389/tcp para LDAP) y luego emite un comando que inicia el transporte cifrado. Cuando llamas, ldapsearch -ZZ ...eso significa que estás invocando StartTLS.
Cuando se utiliza SSL/TLS "real", se conecta al puerto cifrado (636/tcp de forma predeterminada para LDAP), se configura el canal cifrado yentoncesEl inicio de la comunicación del protocolo LDAP tendrá efecto.
Entonces, o te faltan algunas OPTS en tu código PHP para que StartTLS funcione, o deberías usarlas ldaps://hostname/como tu URI LDAP.
Editar:
Aunque es objetivamente correcto, la causa raíz no parece estar en la confusión TLS-StartTLS. La ldap_start_tls()rutina PHP probablemente en realidad invoca StartTLS, por lo que el uso de OP 389/tcpes correcto.

Encontró. Muchas gracias a @Fiisch.

funcionaba como root pero no como apache. Sólo una pregunta, ¿es lo suficientemente seguro?
