Estoy usando Apache 2.4.23 y quiero usar la autenticación Kerberos al acceder a mi intranet. Mi configuración de Apache se ve así (no te irrites por el primer vhost firma2020, que es un vhost temporal porque tenemos un proxy inverso para llegar a un sitio específico desde el exterior, así que tuve que agregar este host virtual)
<VirtualHost 10.160.144.165:443>

No entiendo por qué obtengo acceso simplemente ingresando mi nombre de usuario y contraseña correctos. Esperaría que me bloquearan porque el grupo ldap no está asignado
