Comment 9 for bug 1933116

As a precision of previous message, here is my sssd.conf:

[sssd]
default_domain_suffix = my_domain
full_name_format = %1$s
domains = my_domain
config_file_version = 2
services = nss, pam

[domain/my_domain]
debug_level=9
default_shell = /bin/bash
krb5_store_password_if_offline = True
cache_credentials = True
krb5_realm = MY_DOMAIN
realmd_tags = manages-system joined-with-adcli
id_provider = ad
fallback_homedir = /home/%d/%u
ad_domain = my_domain
use_fully_qualified_names = True
ldap_id_mapping = True
access_provider = ad

After adding 'ad_gpo_access_control = permissive' at the end of file, authentication with samba4 users works again.
