Public bug reported:
sssd in bionic (1.16.1) breaks automounting because it does neither
follow RFC 2307bis-02 nor obeys sssd.conf settings like:
ldap_schema = rfc2307
ldap_autofs_map_object_class = automountMap
ldap_autofs_map_name = automountMapName
ldap_autofs_entry_key = automountKey
On xenial sssd (1.13.4 with the same sssd.conf and ldap server)
automounting works as expected. The related queries/results from a
xenial and a bionic client show the difference:
