Using the SSSD (v1.13.4-34.7.1) joined to a child domain, the modified "ldap_idmap_helper_table_size" directive value in the host sssd.conf is set at the parent domain instead of the child domain, which remains at the default of 10 (the child domain is a not a domain tree).
My understanding is that no "subdomain_provider" directive is needed for this configuration, and the "subdomain_inherit" directive does not support the inheritance of the "ldap_idmap_helper_table_size" directive.
The sanitized sssd.conf:
[sssd]
config_file_version = 2
services = nss,pam,pac
[nss]
filter_users = root
filter_groups = root
[pam]
[pac]
id_provider = ad
access_provider = ad
enumerate = false
cache_credentials = true
ldap_idmap_helper_table_size = 20
ad_site = DarkVixenCorp
ad_access_filter = DOM:LAB.DVC.DARKVIXEN.COM:(memberOf=CN=DARKVIXEN200_G,OU=LDAP,OU=SVS,DC=lab,DC=dvc,DC=darkvixen,DC=com)

Is this a bug fixed with later daemons or is there additional configuration required ?
Many thanks,
