pam_sss(sshd:account): Access denied for user AD

Question

sssd.conf:

[sssd]
domains = corp.com
config_file_version = 2
services = nss, pam

[domain/corp.com]
ad_domain = corp.lecapam.com
krb5_realm = CORP.COM
realmd_tags = manages-system joined-with-samba
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = False
fallback_homedir = /home/%u@%d
access_provider = simple
simple_allow_groups = RootUser,NonRootUser

The issue is, members of NonRootUser AD groups can't make SSH connection, while members of RootUser can, i recently added NonRootUser AD group to configuration and restarted sshd and sssd service.

Errors:
