adcli no puede unirse a AD con la opción LDAPS

Tengo problemas con adcli en ubuntu 18.04 que se actualizó recientemente con la opción ldaps.

Parece que no puede encontrar el nombre corto de AD y tampoco logra conectarse a LDAP incluso cuando se especifica la CA en el comando y con /etc/ldap/ldap.conf

También intenté configurar ldap_uri en la configuración SSSD sin suerte tampoco.
