Additional notes, I've a rather basic/simple setup:
/etc/sssd/sssd.conf
[sssd] services = nss, pam domains = shadowutils,DOMAIN [nss] filter_users = postgres filter_groups = domänen-benutzer [pam] [domain/shadowutils] id_provider = files auth_provider = proxy proxy_pam_target = sssd-shadowutils proxy_fast_alias = True
/etc/sssd/conf.d/domain-ldap.conf
[domain/DOMAIN] id_provider = ldap auth_provider = ldap access_provider = ldap chpass_provider = ldap ldap_uri = ldap://addc.domain.de/ ldap_search_base = dc=domain,dc=de ldap_default_bind_dn = xxx ldap_default_authtok = xxx ldap_user_object_class = user ldap_group_object_class = group ldap_user_name = sAMAccountName ldap_tls_reqcert = demand ldap_tls_cacert = /etc/ssl/domain/DOMAIN_Root_CA.pem # defines user/group schema type ldap_schema = ad # for SID-UID mapping ldap_id_mapping = true # disable case sensitive user names case_sensitive = false # caching credentials cache_credentials = true enumerate = true # access controls ldap_access_order = expire ldap_account_expire_policy = ad override_homedir = /home/%d/%u fallback_homedir = /home/%d/%u default_shell = /bin/bash
cc @pbrezina maybe we broke the proxy provider with 2.0?
